FOX SERIES

The main characteristic of the FOX inverter is its efficient and flexible control of motor speed. In this way, theasynchronous motor can be used in a wider range of applications, with a more regular rotation and a significant reduction ofnoise compared to the older inverters.

The FOX inverter can be used not only in the industrial field, e.g. machines, conveyor belts, etc., but also in the civilfield where its good performance and noiseless operation are essential features for its use.

- High torques at low revolution number

The FOX inverter produces high torques at low revolution number without discontinuity thanks to the automatism that,being activated from 0.1 Hz, assures a safe start of the motor .

- Noise disappearance

With the FOX inverter, those annoying noises typical of the older inverters will never be heard. The noiseless operationof the inverter is due to a proper method of creating the waveform of the voltage that supplies the motor.

- Continuity of operation in power failure state

In case of temporary power failure, the FOX inverter stops and starts again, and keeps the preset controlcharacteristics without having to stop the motor.

- Easy operation

A panel consisting of four keys, one display with four 7-segment digits and three leds allows you to easily operate theFOX inverter.The display and the keys allow you to change all the inverter parameters so as to make it suitable to all applications.The display also shows the values controlled, e.g. frequency or current, and the error codes in case of improper operation.

A programming key device allows to copy the preset control characteristic of the inverter for transferring parametersfrom and to or between inverters.

Besides being controlled from panel, the FOX inverter can be easily remote controlled and programmed through seriesconnection by means of a proper communication protocol.However, the run, stop, speed reversal and change operations are performed, as usual, through terminal board.

FOX

INTRODUCTION

In spite of its compact dimensions, the inverter FOX has several control features. When installed between mains andmotor, the inverter will increase their performance by offering a long continuous service that will result in saving.

FOX SERIES PRODUCT DESCRIPTION

The FOX inverters are converters with D.C. intermediate circuit. When connected with a common single or threephase mains,they produce a threephase, variable-frequency, A.C. voltage, used to control the speed of threephase asynchronous motors.

The control circuit has a microprocessor properly programmed.

The control keyboard allows the user to easiliy and quickly enter any parameter necessary for the required working conditions.

The threephase, variable frequency, alternate voltage, controlled by microprocessor, is delivered to the motor through a powermodule which uses the most recent IGBT technology.The use of microprocessor, IGBT technology and modulation frequency programming, assures an extremely accurate andsilent operation.

The software, properly developed for power electronics, allows for an accurate and quick control of motor speed, start and stoptimes which can be independently adjusted, and other operation conditions:

l Speed control as a function of the load is by current adjustment, thus allowing for automatic adjustment to process.

l Automatic boost that allows for a safe start of the motor by acting on the torque as a function of the load. Presenceof high torques and rotation evenness at very low frequencies too.

l Direct current braking, with programmable duration and value, allowing for a comfortable motor stop.

l Presence of a PID-type inner regulator, which can be freely configured, to control the motor speed and/or torque.

l Presence of a standard series line, with programmable transmission modes, to remote program and/or control theconverter.

Further, the unit is provided with two programmable relay outputs and two programmable opto-insulated digital outputs, foralarms and machine state signalling. It also has an analog output that indicates, through selection, the trend of the main valuesof the inverter.

INSTALLATION GUIDELINES

In order to obtain a safe operation of the unit, assembly and start-up should be performed by skilled personnel only, according to the general regulations concerning safety conditions when working with high currents

or voltages.

Mechanical installationRemoval of the heat produced by the inverter is performed by ventilating with natural air flow, in low power models, and

by means of fan in all other models.When assembling, leave a space of at least 40 mm. from the sides and 150 mm. above and below the inverter, so as

to assure a free circulation of the cooling air. In case of stacking of more units, leave a vertical space of at least 300mm. between them.

The site should assure the ventilation air is free from dust or corrosive gases, otherwise a regular cleaning of the co-oling surfaces must be performed. Avoid, in any case, the condensation of the sprayed fluids. The ambient humidityshould never exceed 90%.

In working conditions, the temperature inside the cabinet should never exceed 40° C. If it should, it will be necessaryto perform a derating of the unit or a forced ventilation so as to avoid air stagnation.

Warning: When calculating the overall dimensions, also consider the space required for installation of anti-noise filters.

Electrical installationThe inverters are designed to operate in an industrial environment where high levels of electro-magnetic disturbance must

be expected. Good installation practice usually ensure trouble-free operation, however it is suggested that a good earthconnection and RFI filters should be used. The RFI filters ensure a reduction of radiated or conducted interference when theinverter is in a interference sensible environment.

To connect the inverter, just remove the cover which protects the power and control terminal boards.The FOX series is designed both for 220V / 240V single phase or three phase supply (FOX2M004...2T022 ) and 380V

/ 460V three phase supply (FOX4T008...4T110 ).For supply cables, we recommend using two-wire (phase + neutral) shielded cable or four-wire (the three phases+earth)

shielded cable, with the earth cable external but parallel to the shield; dimensionning must consider a ∆V on cable notmore than 5% of mains voltage as per EN60204-1.

The same cable can be used for motor connection too. The cable length should never exceed 30 m. If it should, useadditional inductances, series-connected with cables, to balance the parasitic capacities. In this case, a reduction of mo-tor voltage can be noticed.

Warning: The inverter supply must be protected by means of fuses or automatic switch.

Make sure the cables are properly connected and, in particular, check that the earth connection is correctly locked. In caseof shielded supply cables, connect the shield with the G(EARTH) terminal on drive and motor side.

The power cables must be kept separate from the signal cables. The standards require the use of separate raceways.For control cables, use a shielded cable with a section of at least 0.5 mm 2. The shield should be connected with

PE (0V, terminal 16) on drive side only.For connection of reference signals or serial line, use twisted cables.Connect spark quenching units in parallel to relay coils, solenoid valves, remote control switches located near the unit, as

suggested on the following table:

REMOTE CONTROL SWITCH CHARACTERISTICS OF SPARK QUENCHING UNITOR SOLENOID VALVE TYPE

220 V, 240 V > 30 A 0.5 uF + 100 Ohm 1/2 W 250 V

220 V, 240 V < 30 A 0.1 uF + 100 Ohm 1/2 W 250 V

380, 460 V 0.5 uF + 100 Ohm 1/2 W 1000 V

Warning: The protection circuit failure towards earth must ONLY protect the inverter against failurestowards earth, occurring on the motor cable or on the motor itself. It is NOT designed to protect

people who accidentally touch the motor or the corresponding supplying cable.

It is forbidden: to connect PFC devices to output terminals between inverter and motor;to connect capacitors between output terminals or output terminals and earth;

It is not advisable: to connect remote control switches to output terminals between inverter and motor.

WIRING HINT

Note: To connect the inverter it is necessary to conform to the following indications:

1 - Power supply wiring: only the three power wires must be shielded; the ground wire, which is obligatory, must be external to the shield and run parallel to it.2 - Both the inverter side and the motor or filter side of the shield must be grounded.3 - The ferrite toroid must be put on the inverter side of the cable in a way to cover the part of the cable uncovered fromthe shield.4 - The power cables must be kept separated from the signal cables; it is forbidden to install power and signal cables inthe same conduit or duct. It is important to hold motor wiring as far as possible from the power supply wiring.5 - Use high quality motors, with low parasitic capacities towards ground.

The input filter increases leak currents towards ground; so it is advisable use a overcurrent switch with a tripping currentnot lower than 100 mA .

The following drawing shows the wiring method wich is in compliance with the standards.

If the system where the inverter is installed isprovided withovercurrent switch, this one

should be calibrated for a tripping current notlower than 100 mA and for a time not lower than 0,1 sec.Further, it must be able to support high frequencydisturbance events.

Here, the cables section indicated is the lowest onerequired when the length does not exceed 30 m. In thisway, the leakages are reduced and the voltage drop donot exceed 5% of the supply voltage, as specified inEN60204-1 standard.

FOX SERIESOPERATIONOPERATIONOPERATIONOPERATIONOPERATION

Before turning the inverter on, make sure the cover is locked in position. After each turning off,wait some minutes before opening the unit so as to allow the capacitors to discharge.

For safety reasons, at power on or after a reset due to an alarm, the inverter is factory-preset not tostart even with run control in active state. To start the motor, you should set the control first to OFF and then to ON (thissafety precaution can be intentionally cancelled through parameter b-03).

l Turning on

The inverter is not provided with a ON/OFF switch. This operation is performed by appliying the mains voltage. After voltageapplication, the inverter performs a test. If an error is encountered during this test, the display will show the message Ã ErrThe display, consisting of four 7-segment digits, shows both letters and numbers. When turned on, it shows the outputfrequency value ( Ï0Hz with stopped motor).The inverter is factory-preset to control standard motors which operate with voltages and currents having valuescorresponding to the inverter size.

l Run

1 - Connect a 4,7 kOhm potentiometer for speed reference (terminals 24, 25, 26).2 - Connect two contacts for forward and backward run control (terminals 2, 1, and 7/8 ) as shown on page 6.3 - Close the the run contact to start the motor . The motor is started at the frequency selected through the preset ramp

(5 seconds from 0 Hz to maximum frequency).

If the factory - preset values should be modified to adapt the inverter to the application, it canbe made through the control panel where the actual values can be displaied, then modified, andthen permanently stored.

l Stop

To stop the motor, proceed as follows: - Disable the run control. In this way, the motor is stopped with factory-preset ramp (5 seconds from max. frequency

to 0 Hz). - Or set to zero the speed reference potentiometer, so that the user has control over the motor stop.

Caution: in this case the motor is still live.

l The motor does not start

If after enabling the run control, the motor does not start, first check that the connections shown on page 6 have beenperformed, then check that the factory-preset parameters meet the motor characteristics.The parameters can be checked through the P menu. Press the M key until the P menu appears, then, through the Ý ß keys,select the code of the parameter with the value to be checked and press the E key to get its value. Important are the data ofthe motor rating characteristics that can be set through the parameters P-01, P-02, P-09, P-11, P-12 (page 19).

DESCRIPTION

(with option parallel boardonly)

When selecting the analog input, it is possible to change the formula that transforms the reference input signal intothe motor supply frequency through the following parameters:

P-14 determines the minimum frequency (offset); it can assume negative values too.P-15 determines the gain.b-04 enables the formula reversal (a minimum signal corresponds to a maximum frequency).

Let us assume that the input is a 0/10 Vvoltage analog signal:

Direct formula: b-04=0 Inverse formula: b-04=1

volt voltFrif.=((P-01 - P-14) * ----- * P-15) + P-14 Frif. = P-01 - (((P-01 - P-14) * ----- * P-15) + P-14)

In any case Fref. will always be limited between P-73 and P-01.

As a alternative to the above mentioned method, the frequency reference can be selected by re-calling somefrequencies preset through parameters F, by means of some contacts to be connected to 3 of the 5 digital inputcorresponding to terminals 17, 18, 19, 20, 4 of the control terminal board (figures on page 8 and 9).To do so, you must configure as a reference frequency switches, 3 of the 5 inputs with parameters, according to thefollowing order :P-39, P-40, P-41, P-42, P-43. These inputs state will give the result indicated on the following table:

Selects the motor base frequency (rated); this frequency is associated to themotor max. voltage set through P-02.Selects the intermediate frequency.

Selects the voltage applied to the motor as regards the intermediatefrequency.To make this value independent from the inverter supply voltage fluctuationenable the automatic adjustement function of the output voltage by settingb-32=1. In this case, the inverter can be supplied through a voltage higherthan the motor rated one. If b-32=0 then the voltage value setted by P-02must matches the motor rated voltage.The value of the applied voltage can be controlled through the terminal boardby applying a 0/10 V signal to the AUX-V input (term. 22) and setting P-47=10.This voltage is added to the V/F characteristic in a decreasing way,until it is annulled at the intermediate frequency (P-71). (fig. A)

The maximum output voltage value is limited to (P-74*P-02)/100 value.This value can be adjusted through terminal board by applying a 0/10 Vsignal to the AUX-V input (term. 22) and setting P-47=2If b-16=0, the reduction is always active; if b-16=1 the reduction is inactiveduring the ramps, so that the torque is completely available both inacceleration and decelerazione state.

Particular frequencies with which the inverter supplies the motor can causeundesired vibrations to the mechanical parts coupled to the motor.Parameters P-34 and P-35 can be set to exclude two of these frequency.

Defines the frequency interval amplitude, to the left or right of the jump frequency.E.g.:the interval around jump frequency no. 1ranges from (P-34)-(P-36) to (P-34)+(P-36). Note: the two intervals can overlap. To disable an interval, the relatedfrequency set by P-34 or P-35 must be set to 0 Hz.

The output frequency can be limited independently of the maximum and minimumvalues defined by parameters P-01 e P-14.The output frequency can exceed the maximum frequency set by P-01 up to themax. value of 110%. This is done by using the slip compensation function or thespeed feedback with the PID regulator.

JOGGING is a particular run control to advance the motor by small amounts. Itapplies preset frequencies to the motor through parameter F-08 with accelerationand deceleration ramps set through parameters P-25, P-26. It does not allow DCcurrent braking at startup or in stop condition If b-00 = 0: RUN = run, REV =reversal, and the input Ix-JOG handles the jogging control. If RUN and Ix-JOG aresimultaneously enabled the first one enabled will override the other one.If b-00 =1: RUN = forward run, REV = backward run, the Ix-JOG enables the jogging controlthat overrides the normal run control.

0 = 1kHz; 1 = 2 kHz; 2 = 3 kHz; 3 = 6 kHz; 4 = 9 kHz; 5 = 12 kHz; 6 = 15 kHz;7 = 18 kHz. High values of the switching frequency reduce or eliminate the electric"noise" generated by the motor; viceversa, low values give a higher rotation fluidityat low speed, especially if high torques are required.Dead times compensation: it improves the torque and fluidity actions at low speed.

0 defines a natural sine modulation; 1 allows a flat sine modulation which causesa lower inverter heating with high switching frequency values.In case of output frequencies below 5 Hz, a 3 kHz switching frequency isautomatically selected.

5 enables Ix-T1 as ramp selector - 6 enables Ix-T2 as ramp selectorsThe Ix-T1 and Ix-T2 inputs state (page 28), given by the contactsconnected to theterminal board, will give the result shown on the following table:

Note: a) on = closed contact; the controls not used are considered in offstate.

b) When the jogging control Ix-JOG is active (page 28), the ramp pair 4 isautomatically chosen. The acceleration and deceleration times are necessary toswitch from zero Hz to the max. frequency, (P-01), and viceversa.

c) The modification of P-27 can affect the values entered on P-01, P-02,P-21, P-22, P-23, P-24, P-25, P-26 so these values must be rechecked.

d) If a variable signal between 0V and 10V is connected to the AUX-V inputthe accel./decel. ramps can be extended proportionally to this signal value, undercontrol of P-47; (e.g.: 2(s) x 8(V)= 16 s ramp extension).

e)The ramp extension can also be generated if the functions of motorstall and inverter lock are enabled. This actuation is signaled by a flashingGREEN LED and also on terminal board by properly programming OUT1/2/3.

To take advantage of the inverter/motor system features, it is necessary to setthe characteristics of the motor used, through the parameters.P-10 can be calculated, (necessary only if the motor thermal protectionfunction is enabled, par. b-06). The higher the value set, the higher the motorcapacity of supporting currents higher than the rated one.The value of P-12 represents the motor phase resistance in case of starconnection, or 1/3 of the phase resistance in case of delta connection. To getthe proper value of P-12, use the function C-06: - 1) Use M to select the C menu ................................ - 2) Use the ⇑, ⇓⇑, ⇓⇑, ⇓⇑, ⇓⇑, ⇓ keys to select the code 06 ..............

and press E:the display will show the value of C-06 ..................

- 3) Use the ⇑, ⇓⇑, ⇓⇑, ⇓⇑, ⇓⇑, ⇓ keys to select the code 07and press E:

the stator resistence is automatically measured .The display will confirm that the operation has been executed .(To see themeasured value, read the value of P-12 that, if necessary, can be manuallymodified).

0 = standard motor, not servo-ventilated, at low revolution number not able tosupport the rated current (derating), the continuous current of DC braking isreduced by 50% (the motor is able to support a continuous current that is 50%of the rated one).1 = servo-ventilated motor;specify the type of motor used through parameterb-07.The level reached by the protection can be read in d-10, measured in %of the max. thermic overload allowed for the motor. When this level reaches100%, the protection trips and the inverter is locked.

Excessive current or voltage can cause motor stall or inverter lock conditions dueto protections tripping.The aim of the parameter is to set thresholds that, whenexceeded, trip some actions that limit currents and voltages:b-24: if the threshold programmed through P-77 (in acceleration state and if f<P-70, constant torque zone), or through P-78 ((in acceleration state and if f>P-70,constant power zone) is exceeded, the ramp is stopped until the current remainsover this threshold.b-25: if the threshold programmed through P-79 is exceeded (constant speedoperation) the output frequency is reduced at a rate controlled by P-82; As soon asI falls below the theshold the frequency start to increase with the selected ramp.b-26: the ramp is stopped when the voltage on filter capacitors is near theovervoltage threshold; when the V falls under the threshold the ramp start again;NOTE: the function can be unable to prevent the inverter lock in case of high-inertialoads and short ramps.b-27: if the voltage on filter capacitors exceeds the overvoltage threshold, the outputvoltage is set to zero (corresponding to a coast-to-stop). As soon as the voltagereaches safety levels,a free rotation motor pickup is executed and the decelerationramp is restarted.NOTE: too short ramps can lock the inverter by overvoltage.The parameters allows to distinguish between the acceleration or decelerationstate and the constant speed state . In fact, acceleration ramps too shortasregards the motor capacity, or slight reference variations, either intentionalor not, does not mean the motor to be considered in constant acceleration ordeceleration. The switching from one state to the other can be controlledthrough P-85, P-86:P-85 set the indifference range to reference change as regards the constantspeed; P-86, instead, set the time after which, starting from ramp completion,the motor is considered to be in constant speed state.

The parameters compensate for the motor speed reduction when increasingthe applied load (slip), changing the inverter output frequency proportionallyto the applied load. Note: a too quick response (P-33 too short) can causefluctuations in the output frequency. To obtain a good compensation properlyset P-09, P-11, P-12 and if the reference frequency is close to the maximumfrequency, it is advisable to set on P-37 a value beyond 100%

The aim of the function which detects the overload is to signal or avoidexcessive efforts on the load, causing the istantaneous locking of the in-verter and the allarm signalling.The treshold defined by P-55 is in % of the motor rated load as obtainedthrough parameters P-09, P-11.The threshold exceeding can be signalled through terminal board by confi-guring the Ox-GTT output.The parameter P-12 must be accurately set too.P-56 Set how long the overload can exceed the tripping threshold beforethe signalling and the inverter lock functions are enabled

The parameters avoid locking the inverter when happen a short mainsblackout.The mains cut off is signaled on the display and on the terminalboard by configuring one of digital outputs OUT1, OUT2, OUT3.Note: 1)on single phase inverter it is advisable to reduce the P-75 value to theminimum to prevent excessive startup currents. Otherwise it is possible thatthe inverter lock by undervoltage. The alarm is always enabled if the voltagefalls under a given value that depends on the inverter size; 2) the tripping ofthe prevention function sets the output voltage to zero, (coast-to-stop). In thisway, the filter capacitors are not completely discharged thus keeping thecontrol logic active. As soon as the voltage exceeds the threshold (hysteresisof 6%), a pickup phase of motor in free rotation is performed, thus resettingthe speed in force before the tripping.

The aim of the pickup function of motor in free rotation is to avoid the higherthan normal startup currents generated when, for some causes the invertercuts the voltage to the motor, then a subsequent run command makes a startfrom zero Hz with the motor still rotating.This function generates an initial frequency, b-30, equal to or higher than themotor one, by gradually increasing, P-84, the output voltage to 100 % andcontrolling that the current does not exceed a preset threshold set by P-80,(it is advisable that this value should be lightly higher than the currentabsorbed by the motor ) otherwise the output frequency would be reduced andthe voltage would be limited.The delay between the cut off of the motor voltage and when the motor pickupphase start can be controlled by P-81 (demagnetization time).The motor is considered frequency-locked when a given frequency is reachedso that, at full voltage, the current is under the threshold.The motor can thenbe accelerated or decelerated until the reference is reached.b-23 enables the uses of a frequency obtained from an encoder as initialfrequency for motor pickup.The motor pickup function can be enabled through terminal board byconfiguring one of the inputs as Ix-FLY input. If the Ix-FLY input is active, everytime the run control is pressed the motor pickup is performed.

This function is an alternative to the voltage (and torque) boost obtainedthrough parameter P-04 (pag. 24).The output voltage is automaticallyincreased as regards the motor and the connected load characteristics. Theefficiency of the action depends on the accuracy applied when setting theparameters P-09, P-11, P-12.

With the optional board, an encoder or a general frequency signal can be used asfrequency reference or speed feedback.; b-22=1 allows the use of encoder with twochannels. In this way, the number of the detected pulses is multiplied by 4 (theaccuracy increases) and the rotation direction is detected too. The direction can bereversed through the REV control on the terminal board (the choice will have effect onlyif the change occurs when b-21=1). The input for a one-channel encoder, or anotherfrequency transducer (e.g. phonic wheel), is through channel A terminal.b-23=1 set the f-encoder as initial frequency during the free rotation motor pickup.P-59 Set the pulses count time; it affects both the measure accuracy and its updatespeed. At the maximum speed, P-59 should be set to such a value that the numberof pulses counted does not exceed 65536. If both channels are used, the numberof pulses counted is 4 times the one detected on one channel only.. (The valueselected would be active only if b-21=1).

The accuracy of f-encoder depends on the number of counted pulses: its value is 1/N-imp. At low speed, the accuracy couldbe reduced.Setting P-00=5 the f-encoder can be used as frequency reference, or as reference or feedback input of PID regulator.The f-encoder value is on the display at position d-20 as frequency and at d-21 as speed. As 0/10 V analog signal, the f-encodervalue is available on the terminal board by presetting the corresponding analog output: P-48=11 (page 29).The terminal board can signal the following: encoder rotation direction (in positive or negative logic), encoder stopped (no pulseduring the P-59 time) or in rotation state, through digital output configuration. - Encoder power supply.The inverter provides two voltages : +5V (pin 30) and +24V (pin 6).

DESCRIPTIONVALUE

[DEFAULT]The aim of D.C. braking is tokeep the motor locked in a fixedposition, it is not an alternative tothe ramp deceleration. The D.C.braking consist in forcing a directcurrent that depends from thevoltage set by P-28 and theelectrical characteristics of themotor into a motor phase (ph. U).With D.C. braking, the decelera-tion time is shorter than in caseof coast to stop. Sometime, atstartup, it mai be useful to lockthe motor for a preset time beforestarting the acceleration ramp.The braking current intensity canalso be adjusted through theterminal board by means of a 0/10V signal applied to the AUX-Vinput (configured with P-47=3):the current value changesproportionally to the 0/10V signalbetween 0 and the value fixedthrough parameter P-28.The function can also be enabledor disabled through terminal boardby configuring one of theprogrammable inputs (Ix-ENB)as a control.It is always possible to force adirect current on the motor,independently of the valuesassumed by the parameters, byconfiguring one of the terminalboard programable inputs (Ix-DCB) as control of for D.C.braking.During the D.C. braking, atparameter d-00 the displayshows the message " dcb "instead of the frequency.

When the encoder is used as reference or feedback signal b-42 allowsupdating period of the regulator output to be locked to the encoder one (P-59).0: the regulator controls the output frequency; full scale value defined by P-01;1: controls the output voltage; full scale value defined by P-02;The sign of the error signal between reference and feedback is reversed (andthe adjustment effect too).1:the reg. output is added to the freq. reference value or to the voltage valueprovided by the V/F characteristic; 0: the output act as set by b-43.Limits the regulator output in the positive direction; 0 allows the output toassume positive values too.Limits the regulator output in the negative direction; 0 allows the output toassume negative values too.Allows for integral term to match the limits set to the output by b-46 and b-47.Allows the initialization by means of the run control. NOTE: this could causea very slow response of the regulator, even with high gains.The reference value is derived through the setting of the selector parametersshown on the following table.Defines the max. positive excursion of the regulator error expressed in % of thefull scale value.Defines the max. negative excursion of the regulator error expressed in % ofthe full scale valueDefines the regulator update time.

The regulator enabling and the coefficients selection can be made throughterminal control board by configuring two out of the five control inputs as Ix-PID and Ix-P12 input respectively:Ix-PID = 1 the PID regulator is controlled from the terminal board.Ix-P12 = 1 selects the coefficient set N. 1; 0 refers to set 2.When enabling the regulator or changing the coefficients set, the integralterm is used according to the present output and coefficients, by taking intoaccount possible limits applied to the output and to the integral term; thisavoid sudden output changes ("bumpless" operation).If the coefficient change occurs when the error is significant, the systemresponse speed is affected by the integral action weight, as the proportionaland derivative term weight is compensated by the integral term.A max. tolerance interval can be defined for the error that, if exceeded,actuates a signalling available on the terminal board by properly configu-ring one of the digital outputs: OUT1, OUT2, OUT3 .The error tolerance control is enabled when the error falls within the presetinterval for the first time (P-44 value: 21, or 22, or 23). During startuptransient (that is: not before the regulator error falls within the tolerancelimits at least once), it is possible to disable the outputs through P-44 value24, or 25, or 26. The possible sign reversal made by setting b-44=1 hasno importance for tolerance control.The out-of-tolerance signaling available on the digital outputs can beenabled when exceeding one of the two limits (Ox-ERP), or the positive (Ox-EPP) or negative (Ox-EPN) limit only.To facilitate the parameters setting, the following items can be displayed:

reference signal: code d-22 on display,feedback signal: code d-23, "error: code d-24, "integral component: code d-25, "output: code d-26, "

NOTE: The integral term is set to zero if the integral action time is set tothe max. value, i.e. 99.99. The derivative term is null if thederivative action time is set to zero.

Configuration memory error. It is enabled at inverter startup if the configuration memory is notworking properly. To avoid this, try to turn the inverter off and restart it after some minutes.Parameter memory error. It is enabled if the memory contains inconsistent parameters. Causes:accidental loss of parameters (turning off during storage phase), memory failure. In case ofaccidental loss: turn the inverter off and restart it after some minutes. The factory-presetparameters will be stored.

External protection: enabled by the EXTFLT input on terminal board. Autoreset can be enabled onlyif parameter b-11=1.Overcurrent protection: enabled when the output current exceeds, even momentary, the max.allowed threshold to protect the inverter. It signals shortcircuits between phases and to ground too.Overvoltage protection: enabled when the voltage at the filter capacitor ends exceeds the max.programmed threshold to protect the inverter.Undervoltage protection: enabled when the voltage at the filter capacitor ends falls below the min.threshold programmed to avoid troubles due to torque reduction. Autoreset is allowed. If b-37=0,the alarm storage is disabled.Overtemperature protection: enabled when the heat sink temperature exceeds the max. thresholdprogrammed to protect the inverter. Autoreset is not allowed.Inverter overload protection: enabled when the direct current exceeds the max. threshold for themax. allowed time (IxT) to protect the inverter. Autoreset is not allowed.Motor overload protection: enabled when the direct current exceeds the max. threshold for themax. allowed time (I2xT), to protect the motor. The levels and times depend on setting of the motorcharacteristic data. Autoreset is not allowed.Braking resistor overload protection: enabled when the power dissipated by the braking resistorexceeds the max. threshold for the max. allowed time. The levels and times depend on setting ofthe resistor characteristic. Autoreset is not allowed.Protection for momentary motor overload: it is active, after enabling (b-17=1), when the torquedelivered by the motor exceeds the programmed level for the preset time, to protect the connectedmechanical parts or the worked material.Protection for supply phase lack (valid for 3-phase supply only): enabled 30 s. after one of thesupply phases has been disconnected. Autoreset is not allowed.Fuse breakage protection: enabled in case of inner fuse breakage. Autoreset is not allowed.

a) Keyboard reset:simultaneously press the Ý and ß keys : the action will have effect when the keys are released.

b) Terminal board reset:it can only be performed if one of the programmable control inputs has been configured as Ix-

RES. In this case, the reset operation is enabled when switching from active to inactive control.c) Cut the inverter supply off, wait until it is completely off, supply the inverter again.

Serial line

DESCRIPTION

The inverter can communicate with a remote controller through a RS-485 2-wire serial line. In this case, the inverter behaveslike a "slave", i.e. it answers on special controller request only (master). Up to 32 inverters can be parallel connected withaddresses set between 1 and 99 through P - 68.The address 99 is a specialized one since it is expected that it will be used when it is necessary to send a code to all inverterssimultaneously; in this case the reception of the code is assured to all inverters regardless of the individual address, theacknowledgement will be made only from the inverter with address 99.The serial line allows reading and writing all the parameters, forcing the various controls by replacing the keyboard or theterminal board, or forcing the I/O as in a PLC. The parameters involved are:

OPTIONS

AUXILIARY KEYBOARD [ code FOXTST ]

The auxiliary keyboard take the place of the on board keyboard when, formounting reasons, it is not possible to reach the control panel.It performs the same functions as the control panel.As in the control panel, there are: - 4 keys: Enter, Menù, Ý, ß (simultaneously pres Ý and ß to reset the alarm ) - 4 7-segment digit to displays all parameters. - 3 Led indicating: forward run, backward run, storage status. - further 3 Led to indicate the units of parameter value displayed.The auxiliary keyboard is equipped with a 6-wire extension cable, 2 m.long. This cable must be connected : one side to the connector on thecontrol board to the left of control circuit terminals, the other side to theconnector on the front, lower side, of the auxiliary keyboard. Anythingelse is required to operate the auxiliary keyboard.

REMOTE TERMINAL [ code FOXREM ]

LCD contrast adjustment hole

The remote terminal connects to the SIRCO inverter, FOX series,through a 2-wire RS 485 serial line with a programmable Baud Rate .The serial connection allows the remote terminal to control up to 32inverter.The remote terminal supply needs +8/+24 Vdc, normally provided by theFOX series .Operator interface : - 16 character LCD alphanumeric display, possibly backlighted. - 8 keys to program and control the inverter. The STOP, FWD, JOG, and REW keys performs the direct operation of run and stop of an inverter enabled to do so. - 4 signalling Led .A 4-wire terminal block is provided to link the remote terminal toinverters .The dimensions are the same as the auxiliary keyboard.(For the detailed instructions see the specific handbook)

- Wiring the remote terminal:

Remote Terminal shield Inverter control circuit terminals

The inverter and remote terminal factory-preset parameters are so that the correct working of the link is assured.


FOX SERIESOPTIONS

PROGRAMMING KEY [ code FOXPRG ]

The programming key device allows for transferring parameters from and to the FOXinverter or between inverters.The data are stored in a E2PROM type memory, so battery backup is not

necessary.The switch put on upper front of the key allows to write protect the stored data.

To copy data from an inverter to the key or viceversa the keypad panel are used.

PROGRAMMING KEY: use method

- Parameter transmission from the key to the inverter:

- plug the key in the appropriate hole on the upper left hand side of the inverter keypad panel- select the parameter C - 04, go to the code 7 press E.

If the key contains invalid parameters, the factory-preset parameters will be used and the message " Err" will bedisplayed for 4 sec. Otherwise, data will be permanently stored and the confirmation message " done" will be displayedfor 2 sec.

- Parameter transmission from the inverter to the board:

- plug the key in the appropriate hole on the upper left hand side of the inverter keypad panel- select the parameter C - 05, go to the code 7 press E.

If the key is write-protected, the control is interrupted and the message " off" is displayed for 4 sec. Otherwise, theinverter parameters are stored on the key and, at the end of the operation, the message " done" will be displayed for 2sec. to confirm the operation.

ENCODER Optional Board [ code FOXENC ]

The board is necessary to use an Encoder with the inverter. This little board is connected, under the cover, on theleft side of the keypad panel through two mini-connectors; it is not possible to reverse the placement; the twomicroswitches must be directed towards the control terminal block. When ordering the inverter it is possible state theintention to use the encoder: in this case the Encoder Board will be factory connected; otherwise it is possible order theEncoder Board when needed but is mandatory that the mounting operation must be done by skilled personnel only,aware of electronic installation rules.


FOX SERIES CONFORMITY

The FOX inverters are designed in accordance to all provisions of the Directive 89 / 336 / EEC and CE Marking requirements.

The aim of the Directive is to avoid the products causing harmful interference and, at the same time, to ensure that the productswill perform adequately and safely under electromagnetic interference.The standards prevents devices from interferring to radio communication services other than induces malfunction onequipment nearby the product one.

The FOX inverters are electrical equipments designed to control the speed of A.C. motors.They can be installed in cabinets,joined together other parts to form a machinery, or installed inside a machinery.

The FOX inverters can be powered by an industrial AC mains source or by a residential one, but the inverter is not to beconsidered a household tool so it cannot be installed nearby other household appliances.

Is responsibility of the end user, when installing the inverter, to be compliant with the EMC directives.

If the indicated prevention measures are implemented the inverter, normally, can be installed withouth problems concerningEMI.
