The frequency inverter KEBCO COMBIVERT F4-F Synchro is adrive component which is intended for installation in electricalsystems or machines. The frequency inverter is designedexclusively for smooth speed control/regulation of three-phaseinduction motors. The operation of other electrical loads (i.e.heaters, lighting, electronics) is not permitted and can lead to thedestruction of the unit.

1.1 Application

1.2 Moving or rotating parts • Motor shaft• Feed axis and parts connected to it

Prior to doing any work on the machinedisconnect it from the main voltage supply andsecure it against unintended restart!

Be aware of the range of movement of themachine during operation! Bodily injury canresult!

1.3 High operatingtemperatures

Motor housing and braking resistor can attainvery high temperatures! Bodily injury canresult!

• Housing of the motor• Braking resistors

1.4 Extending the service life To avoid premature ageing and/or destructionof the KEBCO COMBIVERT, observe thefollowing instructions!

– Install a switch between the voltage supply and inverter, sothat KEBCO COMBIVERT can be shut off independently.

– Frequent switching on and off of the supply voltage isnot permitted!

– Switching between motor and inverter during operation isprohibited!

– The KEBCO COMBIVERT is to be operated under suitableconditions (see Installation instructions in the F4 PowerStage instruction manual).

1. General Operation Guidlines

1.0 Operating Specifications

1.5 Connection instructions Trouble-free and safe operation of the frequency inverter is onlyguaranteed when the following connection instructions areobserved.When deviated from, malfunctions and damages may occurin isolated cases.

– The frequency inverter KEBCO COMBIVERT is onlydesigned for stationary connection.

– Do not interchange voltage supply wires and motor wires.– Install control and supply lines separately (min. 8 inch

distance).– Connect control terminals only to devices (relay, switch,

potentiometer), that are suitable for low voltage operation.– Use shielded/twisted control lines. Connect the shield only to

the ground terminals on the inverter. Do not connect the otherend.

– Use shielded motor cables. Connect shield to the groundterminal of the inverter and terminate the other end to themotor housing. Make sure the connection is very good. Anyincrease in resistance can lead to interference problems.

– Ground the frequency inverter using a heavy gauge groundstrap or mount the inverter to a bare metal panel for bestresults. Always keep ground wires as short as possible andavoid ground loops.

1.6 Interference protectionof electric systems

The KEBCO COMBIVERT generates high frequencyelectromagnetic interference. To reduce interference, that mayeffect electric systems in the vicinity of the frequency inverter,consider following:

– Install the frequency inverter in metal enclosure.– Shield motor cables. The shield must be connected to

ground terminal of the frequency inverter. The shielding shallnot be used as a protective ground. A separate ground wireis required for this. Only a continuous shield without breaksor splices should be used.

– Ground the inverter to the machine ground with a heavygauge ground strap.

– Use KEBCO radio interference suppression filters.


The connections on the control terminal strip andencoder inputs are electrically isolated. Make surethese control connections are not connected orgrounded to the high voltage supply.

7


The control and power inputs of the frequency inverter areprotected against external interference.

For additional reliability and protection againstmalfunctions due to external interference followthese measures:

1.7 Interference protection ofthe frequency inverter

– Use a line reactor or choke, when the mains voltage is affectedby the connection of large loads (i.e. >100 hp), reactive-powercompensation equipment, HF-furnaces or extruders etc.

– Suppress all inductive loads (solenoid valves, relays,electromagnets) with RC elements or similar devices to absorbthe energy released when the unit is switched off.

– Twisted pair cables protect against inductive interferencevoltage, shielding provides protection against capacitiveinterference voltage. Optimal protection is achieved by usingtwisted and shielded cables keeping a minimum of 8 inchesbetween them and cables carrying high voltage.

- Control wires should cross high voltage power cables at rightangles.

1) When an external supply is connected to terminals 23 and 11, the microprocessor's power supply is derived fromthis supply, i.e the control stage is ON without high voltage applied to the power stage. This feature is useful when itis necessary to maintain the function of the encoder and the processing along with it. The 24VDC control supplyshould be turned on before the high voltage to eliminate false triggering of the inputs and outputs.

3 F4F encoder input resistance: Between the A+ and A-, B+ and B- and C+ andC- inputs, a 330 ohm resistor is used to create a low impedance input thusminimizing noise. If more than one inverter is connected to the sameencoder, these 330 ohm resistances are place in parallel. Therefore verifythe maximum load current of the output signals of the encoder. Generallythe maximum number on inverters per encoder is 3. KEBCO can supplyencoder signal amplifers when it is necessary to connect serveral invertersto one encoder.

3. Operation

Due to calculation and measurement accuracies, tolerances with the current and torquedisplays as well as with the switching levels , must be taken into consideration. The giventolerances (see parameter description) refer to the respective maximum values whendimensioning the KEBCO COMBIVERT: Motor = 1:1.Dependent on the data from the motor manufacturer, larger tolerances are possible, due to theusual variations in the motor parameters and temperature drifts.

The internal settings of the inverter are based on the size of the inverterand the size of the connected motor. The inverter comes from the factorywith the motor parameters adjusted for 1:1 dimension between a KEBCOgearmotor and inverter. These standard values are listed on page 28.

Since any motor can be used with the KEBCO COMBIVERT, the usermust make the necessary changes to the data in the motor parametersCP.25...31 when a motor other than a KEBCO motor is used or when thedimensioning is not 1:1. This readjusts the current controller, torquecurve and torque limit providing optimum performance from the inverterand motor.

6. Initial Start Up

Supply voltage connectionsThe 3 phase 230VAC or 480VAC supply voltage should be connectedto terminals L1, L2, L3.

Compare the rated input voltage listed on the nameplate of theF4F to the line voltage connected to the power terminals L1, L2,L3. They should be the same. Connecting 480V supply voltageto a 230V inverter will result in destruction of the unit.

Motor connectionsConsult the F4F power stage manual to verify the proper wire size forthe motor connections. The motor leads should always be shieldedwith the shield terminated only to the inverter not the motor. Keep allmotor leads at least 8 inches away from parallel running control lines.

The three phases on the motor can be connected in any order to theU,V,W power terminals on the inverter. During the initial start up ofthe system, two phases may need to be switched to achieve properrotation of the motor.

If the motor has a normally closed thermal switch or PTC (positivetemperature coefficient) sensor in the windings, it should be con-nected to the OH terminals next to the U,V,W terminals.

Regen resistor connectionsIn most applications some type of regen resistor will be required. Thisresistor should be connected to the PA and PB power terminals.Long leads (greater than 15 inches) between the inverter and theresistor should always be twisted and shielded.

Encoder connectionsUse the feedback cable as supplied by KEBCO to connect the en-coder on the motor to the F4F inverter. The high density 15 pin DBconnector should be connected to the 15 pin DB connector on theinverter.

If you are using a KEBCO motor or gearmotor you can connect themilitary style 12 pin connector to the motor. Be sure to thread theconnector on all the way. When using a motor other than a KEBCOmotor, it is best to use the KEBCO encoder cable which has the highdensity 15 pin DB connector at one end and bare wires at the other.The bare wire end of the cable can then be terminated on a terminalstrip or a special connector.

When using a terminal strip as a connecting device, be sure toconnect the shield from one side of the terminal strip to theother.

Open Loop Problems Cause / SolutionVerify the control connections are wired as indicated onpage 33.

The torque load is greater than the torque limit of themotor. The inverter drives the motor with maximumcurrent until the electronic overload function is triggered.Remove motor from load and verify the motor shaftspins free and the input to the load (i.e. gearbox input)also spins free. If the motor runs when not connected tothe load, but does not run when connected, the loadhas too much friction or the motor is not sized largeenough.

One of the motor power leads is not connected. Turnthe supply voltage off, wait five minutes, and verifyconnections to the power terminals U,V,W.

The temperature sensor in the motor is not connected.Verify the motor temperature sensor is connected to theOH terminals. If no sensor is used, the OH terminalsshould be jumped together.

Encoder or encoder cable is defective. Refer to pages11 and 12 to verify continuity of the cable connectionsbetween the two end connectors and check for propershielding. Verify encoder signals.

Verify the jumpers are installed between terminals 1and 10 and the forward jog switch is working.

Cause / Solution

Encoder or encoder cable is defective. Refer to page 11and 12 to verify continuity of the cable connectionsbetween the two ends and check for proper shielding.Verify encoder signals. Make sure encoder pulse/revand direction (CP.33... CP.35) are adjusted properly.

Verify motor data is entered correctly. Verify load andmechanical system. Look for excessive friction.

7.0 Speed Regulator Adjustment

7.0 Speed regulator adjustmentAdjustment of the speed regulators is necessary to achieve optimum performance from theF4F system. This process is best done through the use of the COMBISCOPE program; asimulated oscilloscope on a PC computer. This oscilloscope can be used to plot and visualizeimportant data such as set speed, motor speed, motor current, and motor torque.

For specific information regarding the COMBISCOPE program, please refer to the COMBIVISinstruction manual. A basic overview of the operation of the program as it relates to theadjustment of the speed regulators will be presented on the following pages.

The goal is to adjust the speed regulators to give the best performance to a square wavespeed command. The jog function of the F4F can be used to create the square wave speedcommand.

Before getting started the following steps should be completed first.

1. The "Initial Start Up" sequence as outlined on the previous pages should be completed.2. The motor should be connected to the actual load.3. Flux vector control should be on; CP.32 = on.4. The jog buttons used during the initial set up, will be used again.5. Adjust the jog speed for 1000 rpm; CP.11 = 1000.6. Verify operation by enabling the drive ( signal at terminal 1) and closing the forward jog

switch. The system should jog forward at 1000rpm. Note: it will be an abrupt startand stop because the system is accelerating and decelerating on the torque limitnot the programmed acceleration and deceleration times.

The program COMBISCOPE can be used to monitor the motor speed and torque in order toadjust the speed regulation gains. COMISCOPE is a function of COMBIVIS 5 for Windows

Before starting the program, connect the serial port on the keypad operator of the inverterto the serial port of the computer using the KEBCO serial cable. When the program starts,it will read the inverter and adjust itself accordingly. If the inverter is not connected, a dialogbox will open displaying No inverter found. It will prompt you to make a selection weatheror not you would like the program to search for the inverter for you at different baud rates orselect “no” and then select the proper inverter type manually. 86:F4F version 1.23(roundtable).

If you do choose to have the program find the inverter, and it fails to find it. The option is stillavailable to select the inverter manually. You may want to verify your cable connections, Comport settings, baud rates both in the inverter and in the PC.

Once the program is running click on the “View” menu at the top of the screen. Then click on“Inverter Scope” in the pull down "View" menu.

7.6 PI - regulator adjustment tips

The following tips should be considered before starting the adjustment process.

• CP12 is the proportional term of the torque command. This parameter controls themagnitude of the instantaneous torque command. The instantaneous torquecommand is defined: (set speed - actual speed) x CP12. (see block diagrambelow)

• CP.13 is the integral term of the torque command. This parameter controls themagnitude of the average torque command. It is defined: S (set speed - actualspeed) x CP.13. (see block diagram below)

• Always make adjustments with the maximum load.

• Always adjust the proportional gain CP12 before the integral gain CP.13.

• Generally, larger motors will require larger values.

• High inertia loads will require high proportional gains and low integral gains.

• High friction loads will require both the proportional and integral gains to be high.

• Instability will result if the integral gain is greater than the proportional gain.

• Once settings are identified, the settings can be used for future implementations ofthe same system, i.e. serial production of machines.

• One trace for each channel will be displayed. The vertical and horizontal scalescan be further adjusted after the trace is made for better viewing.

• To make another measurement, simply press "play" to set the trigger and thenactivate the forward jog.

7.7 PI - regulator adjustment

The following plots can be used as a guide in the process of adjusting the PI speedregulator. The plots were made using a 5 hp motor with an inertia mismatch of 5:1,load:motor.

This is the initial response us-ing the factory settings. Notethe over shoot of the actualspeed. This indicates the pro-portional gain is not set highenough.

On all of these plots, the actualspeed will lag behind the setspeed during acceleration anddeceleration. This is as a resultof the torque limit establishedby the sizing of the inverter andmotor. This limit will always bepresent and must be consid-ered as the maximum rate ofchange possible when estab-lishing the motion profile in themotion control.

In figure 2 the proportional gainwas raised to 3500. The over-shoot is now gone. If theproportional gain is set too high,oscillations will occur. This typi-cally appears as high frequencyvibrations in the motor. Thisoscillation can be visualizedon the torque curve. See Fig.3.

Figure 3 shows the result whenthe proportional gain is set toohigh. Oscillations develope inthe torque loop. Lower the gainuntil the oscillation stops thenlower it an additional 20% forsafety margin.

In figure 4, a friction torque loadequal to 75% of the motor'srated torque was applied. Inaddition the integral gain(CP13) was reduced. The re-sult is that the actual speednever quite reaches the setspeed. This problem occurstypically when the load has ahigh friction component and notjust pure inertia. As a result it isnecessary to set the integralgain (CP13) higher when driv-ing high friction loads.

In figure 5, the same frictiontorque load exists as in figure4. The integral gain was in-creased to provide better cor-rection, eliminating the speedlag during constant run.

Figure 7 demonstrates the re-sult of increasing the integralgain too much. Speed changesresult in torque oscillations.When this occurs the integralgain (CP13) must be reduceduntil the oscillation stops.

In figure 6 the friction torqueload is removed leaving onlythe inertia component. As aresult the integral gain (CP.13)may need to be reduced.

3. Disabling drive (terminal #1 off or drive fault) while in synchronization mode willremove ALL control from motor (motor coast to stop). To restart synchronization,angular deviation must first be reset and then the drive must be enabled(momentary signal at terminal #2, maintain signal at terminal #1). See timing diagramnote: A

4. Turning off synchronization mode (terminal #3 off) results in follower system decel-erating to a stop (deceleration time = 0.1 s, or at torque limit). This can be used for aquick stop or E-stop condition.

5. The system can be jogged manually by turning off synchronization mode (terminal #3off) and using the jog input (terminal #7). The follower system moves as long as thesignal at terminal #7 is maintained


8.1.3 Operational sequence

47


Connect the motor and start up the drive as specified in section 6 "Initial Start Up". Onceoperation is verified, turn the power off and wire control connection according to thediagram shown in section 8.1.2. Then place the drive in standby mode (signal at terminal#1 off) and turn the power back on.

Parameter Adjustment

1. Maximum run speed. The value that is entered in parameter CP.7 will be theMaximum speed that the follower system will operate at regardless of the master speedand electronic gear ratio.

2. Jog speed. The value that is entered into parameter CP.8 will be the speed that thefollower system will run at when put into jog mode. Keep in mind that the jog function isdisabled when the drive is in synchronization mode.

3. Angular deviation warning level. Parameter CP.10 (Display shows 0.CP.10) willprogram thelevel of angular deviation between the master and the follower that will triggerthe angular deviation warning( digital output, terminal #8).

NOTE: Terminal #8 may also be reprogrammed if the application calls for a different function.adjust CP.24 (display shows 0.CP.24) to one of functions listed in the table.

4. Speed level of digital output (terminal #9). Parameter CP.11 (Display show0.CP.11) will program the followers speed level that will trigger the low speed warning(digital output, terminal #9).

5. Speed regulator adjustment. This is the adjustment of how hard or quick the driveresponds to the master speed signal. This adjustment is covered in-depth in section 7.

6. Proportional synchronization controller , parameter CP.14 (display shows 0.CP.14)determines if the drive operates in speed synchronous mode or angular synchronous mode(Shaft Lock). If the value in parameter CP.14 = 0, than the drive is operating in speedsynchronous mode. If the value in parameter CP.14 = 1 or greater, then the drive isoperating in angular synchronous mode. The larger the value the tighter the angularcontrol. Too high of a value will cause oscillations at the motor. If this happens lowervalue of CP.14 30%


8.1.4 Set up of drive

7. Electronic gear ratio #1 is programmed in parameter CP.15 (Display shows 0.CP.15)This is the gear ratio between the follower and the master system.

Example: CP.15 = 2, follower speed 2 x master speedCP.15 = 0.5, follower speed .5 x master speed

If the electronic gear ratio needs to be trimmed by an analog signal see section8.3 Master / follower synchronization with analog trim

If more than 1 electronic gear ratio is needed see section8.4 Master / follower synchronization with digital advance and retard.

8. Encoder set up. During the initial set up of the drive the follower encoder wasprogrammed with parameter CP.32 and CP.33. Now the master encoder must be set up.

The pulses per revolution for the master encoder must be entered into parameter CP.34.Once the master system is started and the follower synchronizes with the master, if thedirection of the follower is moving in the opposite direction that is desired then parameterCP.35 must be adjusted. If parameter CP.35 displays "off" program it for "on" or visa versa(MUST press enter for change to become valid).

8.2 Master / follower synchronization with correction

The following section will outline master / follower synchronization applicationsthat use two sensors to automatically correct for mis-matched gear ratio. Beforethis application can be implemented section 6, "Initial Start Up" and section 8.1,"Master / follower synchronization" MUST be completed.


A helical or worm gear box will never have an exact integer ratio. As a resultthe electronic gear ratio adjustment in the F4F will need to be used tocompensate for the mismatch between the systems. It will not be possible tocompensate entirely for the difference. As a result the follower system willcreep in relation to the master.

To compensate for this, two sensors are used. One on the master system andone on the follower. Each sensor looks for a marker and will continually givepulse signals to the drive as the conveyor moves, i.e. each revolution of thedrive pulley, or each product holder.

The signal from the master is the gate signal and the signal from the followeris the correction signal. The gate signal is used to gate the correction signal.If the gate signal is not active when the correction signal is active , the F4Fignores the correction signal. The signal must be at least 4mSec in width forproper operation. The speed at which the marker passes the sensor and thewidth of the marker control the pulse width.

The electronic gear ratio is adjusted such that the follower system continuallycreeps forward in relation to the master. Note this creep need not be muchmore than a few thousands of a inch, only enough to cause the gate on thecorrection signals to overlap. When the two signals overlap, the F4F causesthe follower system to fall back by an adjusted number of degrees at thefollower motor. This correction re-synchronizes the system to the optimumposition. Depending on the system, the correction could take place as often asonce every few pieces of product or as infrequent as once an hour. Eachsystem presents a different situation.

• The system must synchronize with the master speed profile provided viaencoder signal

• The master encoder pulse per. revolution and direction can beprogrammed

• The follower encoder pulse per. revolution and direction can beprogrammed.

• The desired speed of the follower can be adjusted via electronic gear ratio• The correction for mismatched gear ratio's will be corrected for

2. Synchronization mode turned on (maintain signal at terminal #3) The followersystem's angular deviation is reset to zero and synchronization with master encodersignal begins.

3. Disabling drive (terminal #1 off or drive fault) while in synchronization modewill remove ALL control from motor (motor coast to stop). To restartsynchronization, angular deviation must first be reset and then the drivemust be enabled (momentary signal at terminal #2, maintain signal at terminal#1). See timing diagram note: A

5. The system can be jogged manually by turning off synchronization mode (terminal #3off) and using the jog input (terminal #7). The follower system moves as long as thesignal at terminal #7 is maintained.

6. When the gate signal (terminal #5) and the correction signal (terminal #4) overlap, theF4F causes the follower system to fall back by an adjusted number of degrees at thefollower motor. The number of degrees is programmed in parameter Cp.9. Thiscorrection re-synchronizes the system to the optimum position. Depending on thesystem, the correction could take place as often as once every few pieces of productor as infrequent as once an hour. Each system presents a different situation.

Connect the motor and start up the drive as specified in section 6 "Initial Start Up"andsectio 8.1 "Master / Follower synchronization". Once operation is verified, turn thepower off and wire control connection according to the diagram shown in section 8.2.2.Then place the drive in standby mode (signal at terminal #1 off) and turn the power backon.

For this application two photoeye's or proximity sensors must be used. Refer to section8.2.2 "Control Wiring - Master follower Synchronization with Correction"


The amount of correction that takes place when the correction function is initiated, isprogrammed in parameter CP.9.

CP.9 = Degree's of rotation between correction signals x 0.5

Example:

Follower system

40 degrees at the motor between each correction signal

40 degrees x 0.5 = 20 degrees

CP.9 = 20 Degrees

8.3 Master / Follower Synchronization with Analog Trim

Connect the motor and start up the drive as specified in section 6 "Initial Start Up"andsection 8.1 "Master / Follower Synchronization". Once operation is verified, turn thepower off and wire control connection according to the diagram shown in section 8.3.2.Then place the drive in standby mode (signal at terminal #1 off) and turn the power backon.

Parameter adjustment

For this application to work properly, the analog input must be reprogrammed. Oncethe analog input is reprogrammed the synchronous gear ratio of the follower will beadjusted by the analog input signal. Below is the process for reprogramming theanalog input as well as the parameters that influence the analog gear ratio.

Reprogramming of the analog input

1. Power turned on and the drive disabled (remove signal from terminal #1)

2. Program parameter CP.20 to a value of 8 (note: Must press enter for value toactivated). This will reprogram the analog input to take control of synchronousgear ratio in a forward (+) direction of rotation. If a reverse (-)direction ofrotation is desired program parameter CP.20 for a value of 9.

Adjustment of the analog input

Once the analog input is programmed for an analog gear ratio input, the electronicgear ratio has no function. This means that the analog signal will take full control ofthe synchronous gear ratio. By default the analog gear ratio is 0.5:1 ... 2.5:1 with a0... 10Vdc analog input signal.

Example:0Vdc signal on terminal 16 = 0.5:1 gear ratio10Vdc signal on terminal 16 = 2.5:1 gear ratio.

For all other adjustment ranges the analog input must be scaled by adjusting param-eters CP.21...CP.23. A description and example of each of these parameters canbe found on the following pages.



58

CP.21 - Analog input gain.

Parameter CP.21 controls the overall gear ratio range that is influenced by the 0...10Vdcanalog signal.

Example: see figure 8.3.4a

A) CP.21 = 1.0 0.5:1...2.5:1 gear ratio 0...10Vdc analog signal (Default)

B) Cp.21 = 0.5 0.5:1...1.5:1 gear ratio 0...10Vdc analog signal

C) Cp.21 = 2.0 0.5:1...3.5:1 gear ratio 0...10Vdc analog signal

Parameter CP.22 determines at which voltage on the analog input gives the minimumgear ratio.

Connect the motor and start up the drive as specified in section 6 "Initial Start Up" andsection 8.1 "Master / Follower Synchronization". Once operation is verified, turn thepower off and wire control connection according to the diagram shown in section 8.4.2.Then place the drive in standby mode (signal at terminal #1 off) and turn the power backon.

Write down the values that have already been programmed in parameters 0.CP.10 thru0.CP.14, 0.CP.24, and 0.CP.36. These values will need to be entered again during theset up of this application.


For this application to work properly, the digital inputs must be reprogrammed. Byreprogramming the digital inputs the user gains access to new parameters that must beprogrammed. Programming of these parameters is only possible when a digitalsignal is applied to the additional gear ratio inputs. This will be explained in theprocess below.

• 1.CP.10 = Electronic Gear ratio #2 angular deviation warning level• 1.CP.11= Electronic Gear ratio #2 speed level• 1.CP.12 = Electronic Gear ratio #2 proportional gain speed control• 1.CP.13 = Electronic Gear ratio #2 intragal gain speed controller• 1.CP.14 = Electronic Gear ratio #2 proportional synchronization controller• 1.CP.24 = Electronic Gear ratio #2 digital out D1 switching condition• 1.CP.36 = Electronic Gear ratio #2 speed control on /off

• 2.CP.10 = Electronic Gear ratio #3 angular deviation warning level• 2.CP.11= Electronic Gear ratio #3 speed level• 2.CP.12 = Electronic Gear ratio #3 proportional gain speed control• 2.CP.13 = Electronic Gear ratio #3 intergral gain speed controller• 2.CP.14 = Electronic Gear ratio #3 proportional synchronization controller• 2.CP.24 = Electronic Gear ratio #3 digital out D1 switching condition• 2.CP.36 = Electronic Gear ratio #3 speed control on /off

Reprogramming of the digital inputs

1. Power turned on and the drive disabled (remove signal from terminal #1)

2. Adjust parameter CP.18 to a value of 1(note: Must press enter for value to beactive). This will reprogram terminal #4

3. Adjust parameter CP.19 to a value of 1(note: Must press enter for value to active).This will reprogram terminal #6

Programming the maximum speed and the speed regulators

1. Turn on electronic gear ratio #2 (maintain signal at terminal #6).

2. Re-enter the values that were entered into parameters 0.CP.10...14, 0.CP.24, and0.CP.36 during the "Initial Start Up", "Master / Follower Synchronization 8.1", and"Adjustment of the Speed Regulators" sections. The display will now show a "1" infront of the CP. parameters that previously showed a" 0" (Example = 1.CP.10,1.CP.11). If the display does not show a "1", there is no signal maintained at terminal#4 or the digital input has not been programmed properly in parameter CP.18.

3. Turn off electronic gear ratio #2 ( remove signal on terminal #6) and turn on electronicgear atio #3 (maintain signal at terminal #4).

4. Re-enter the values that were entered into parameters 0.CP.10...14, 0.CP.24, and0.CP.36 during the "Initial Start Up", "Master / Follower Synchronization 8.1", and"Adjustment of the Speed Regulators" sections. The display will now show a "2" in frontof the CP. addresses instead of a "1" like in step #2 (Example = 2.CP.10, 2.CP.11). Ifthe display does not show a "2", there is no signal maintained at terminal #6 or thedigital input has not been programmed properly in parameter #19.

Programming of additional electronic gear ratios

1. Enabled drive (maintain signal on terminal #1)

2. Synchronization mode on (maintain signal at terminal #3), then start master system.This is done to verify system operations of electronic gear ratio #1.

3. Activate electronic gear ratio #2 (maintain signal on terminal #6) Follower will run with agear ratio of 1:1.

4. Adjust CP.16 to desired value for electronic gear ratio #2.

5. Turn off electronic gear ratio #2 ( remove signal on terminal #6) and turn on electronicgear ratio #3 (maintain signal at terminal #4).

6. Adjust CP.17 to desired value for electronic gear ratio #3.

7. Electronic gear ratio #1 = No signal applied to terminals #4 or #6Electronic gear ratio #2 = Signal maintained on terminal #6, no signal on terminal #4Electronic gear ratio #3 = No signal on terminal #6, signal maintained on terminal #4

If a signal is applied to terminal #4 and #6 at the same time, terminal #6 has priority.(Electronic gear ratio #2 active).
