5-200

Communications error processing (y02 for port 1 and y12 for port 2) y02 or y12 specifies the error processing to be performed if an RS-485 communications error occurs. RS-485 communications errors include logical errors (such as address error, parity error, framing error), transmission protocol error, and physical errors (such as no-response error specified by y08 and y18). The inverter can recognize such an error only when it is configured with a run or frequency command sourced through the RS-485 communications link and it is running. If none of run and frequency commands is sourced through the RS-485 communications link or the inverter is not running, the inverter does not recognize any error occurrence.

Data for y02, y12 Function

0 Immediately trip, displaying an RS-485 communications error (er8 for y02 and erp for y12). (The inverter stops with alarm issue.)

1 Run during the period specified by the error processing timer (y03, y13), display an RS-485 communications error (er8 for y02 and erp for y12), and then stop operation. (The inverter stops with alarm issue.)

2

Retry communication during the period specified by the error processing timer (y03, y13). If a communications link is recovered, continue operation. Otherwise, display an RS-485 communications error (er8 for y02 and erp for y12) and stop operation. (The inverter stops with alarm issue.)

3 Continue to run even when a communications error occurs.

For details, refer to the RS-485 Communication User's Manual (MEH448).

Timer (y03 for port 1 and y13 for port 2) y03 or y13 specifies an error processing timer. If the timer count has elapsed due to no response from the other end when a query has been issued, the inverter interprets it as an error occurrence. See the "No-response error detection time (y08, y18)" given on the next page. - Data setting range: 0.0 to 60.0 (s)

Baud rate (y04 for port 1 and y14 for port 2)

Data for y04 and y14 Transmission speed (bps)

0 2400

1 4800

2 9600

3 19200

y04 or y14 specifies the transmission speed for RS-485 communication. For FRENIC Loader (via the RS-485 communications link), specify the transmission speed that matches the connected computer.

4 38400

Data length (y05 for port 1 and y15 for port 2)

Data for y05 and y15 Data length

0 8 bits

1 7 bits

y05 or y15 specifies the character length for RS-485 communication. For FRENIC Loader (via the RS-485 communications link), no setting is required since Loader automatically sets 8 bits. (The same applies to the Modbus RTU protocol.)

Parity check (y06 for port 1 and y16 for port 2)

Data for y06 and y16 Parity

0 None (2 stop bits for Modbus RTU)

1 Even parity (1 stop bit for Modbus RTU)

2 Odd parity (1 stop bit for Modbus RTU)

y06 or y16 specifies the property of the parity bit. For FRENIC Loader, no setting is required since Loader automatically sets the even parity.

3 None (1 stop bit for Modbus RTU)

Stop bits (y07 for port 1 and y17 for port 2)

Data for y07 and y17 Stop bit(s)

0 2 bits

1 1 bit

y07 or y17 specifies the number of stop bits.For FRENIC Loader, no setting is required since Loader automatically sets 1 bit. For the Modbus RTU protocol, no setting is required since the stop bits are automatically determined associated with the property of parity bits.

No-response error detection time (y08 for port 1 and y18 for port 2)

Data for y08 and y18 Function

0 No detection

1 to 60 1 to 60 s

y08 or y18 specifies the time interval from when the inverter detects no access until it enters communications error alarm mode due to network failure and processes the communications error. This applies to a mechanical system that always accesses its station within a predetermined interval during communications using the RS-485 communications link. For the processing of communications errors, refer to y02 and y12.

Response interval (y09 for port 1 and y19 for port 2) y09 or y19 specifies the latency time after the end of receiving a query sent from the host equipment (such as a computer or PLC) until the start of sending the response. This function allows using equipment whose response time is slow while a network requires quick response, enabling the inverter to send a response timely by the latency time setting. - Data setting range: 0.00 to 1.00 (s)

T1 = Response interval + α where α is the processing time inside the inverter. This time may vary depending on the processing status and the command processed in the inverter.

For details, refer to the RS-485 Communication User's Manual (MEH448).

When setting the inverter with FRENIC Loader via the RS-485 communications link, pay sufficient attention to the performance and/or configuration of the PC and protocol converter such as RS-485−RS-232Cconverter. Note that some protocol converters monitor the communications status and switch the sending/receiving of transmission data by a timer.

Protocol selection (y10 for port 1)

Data for y10 Protocol

0 Modbus RTU protocol

1 FRENIC Loader protocol

y10 specifies the communications protocol for port 1. For FRENIC Loader (via the RS-485 communications link), only y10 can be used for protocol selection. Set the y10 data at "1." 2 Fuji general-purpose

Protocol selection (y20 for port 2)

Data for y20 Protocol

0 Modbus RTU protocol

y20 specifies the communications protocol for port 2.

2 Fuji general-purpose inverter protocol

y97 Communication Data Storage Selection A nonvolatile storage in the inverter has a limited number of rewritable times (100,000 to 1,000,000 times). Saving data into the storage so many times unnecessarily will no longer allow the storage to save data, causing memory errors. For frequent data writing via the communications link, therefore, a temporary storage is provided instead of the nonvolatile storage. To use the temporary storage, set the y97 data at "1." Using the temporary storage reduces the number of data writing times into the nonvolatile storage, preventing memory errors. Setting the y97 data at "2" saves all data written in the temporary storage into the nonvolatile one. Changing the y97 data requires simultaneous keying of and / keys.

Data for y97 Function

0 Save into nonvolatile storage (Rewritable times limited)

1 Write into temporary storage (Rewritable times unlimited)

2 Save all data from temporary storage to nonvolatile one (After saving data, the data automatically returns to "1.")

y99 Loader Link Function (Mode selection)

This is a link switching function for FRENIC Loader. Rewriting the data of y99 to enable RS-485 communications from Loader helps Loader send the inverter the frequency and/or run commands. Since the data to be set in the function code of the inverter is automatically set by Loader, no keypad operation is required. While Loader is selected as the source of the run command, if the computer runs out of control and cannot be stopped by a stop command sent from Loader, disconnect the RS-485 communications cable from the port 1 or the USB cable, connect a keypad instead, and reset the y99 data to "0." This setting "0" in y99 means that the run and frequency command source specified by function code H30 takes place instead of FRENIC Loader. Note that the inverter cannot save the setting of y99. When power is turned off, the data in y99 is lost (y99 is reset to "0").

FRENIC-MEGA series of inverters is equipped with a number of function codes to match a variety of motor operations required in your system. Refer to Chapter 5 "FUNCTION CODES" for details of the function codes. The function codes have functional relationship each other. Several special function codes also work with execution priority each other depending on their functions or data settings. This chapter explains the main block diagrams for control logic in the inverter. You are requested to fully understand the inverter's control logic together with the function codes in order to set the function code data correctly. The block diagrams contained in this chapter show only function codes having mutual relationship. For the function codes that work independently and for detailed explanation of each function code, refer to Chapter 5 "FUNCTION CODES."

6.1 Symbols Used in Block Diagrams and their Meanings Table 6.1 lists symbols commonly used in block diagrams and their meanings with some examples.

Table 6.1 Symbols and Meanings

Symbol Meaning Symbol Meaning

High limiter: Limits the upper value by a constant or data set to a function code.

Switch controlled by a terminal command. In the example shown on the left, the enable communications link command LE assigned to one of the digital input terminals from [X1] to [X9] controls the switch.

Low limiter: Limits the lower value by a constant or data set to a function code.

OR logic: In normal logic, if any input is ON, then C = ON. Only if all inputs are OFF, then C = OFF.

Zero limiter: Prevents data from dropping to a negative value.

NOR (Not-OR) logic: In normal logic, if any input is OFF, then C = ON. If all inputs are ON, C = OFF.

Gain multiplier for reference frequencies given by current and/or voltage input or for analog output signals. C = A × B

AND logic: In normal logic, only if A = ON and B = ON, then C = ON. Otherwise, C = OFF.

Adder for 2 signals or values. C = A + B If B is negative then C = A – B (acting as a subtracter).

NOT logic: In normal logic, if A = ON, then B = OFF, and vice versa.

7.2 Overview of Operation Modes FRENIC-MEGA features the following three operation modes:

■ Running mode : After powered ON, the inverter automatically enters this mode. This mode allows you to specify the reference frequency, PID command

value and etc., and run/stop the motor with the / keys. It is also possible to monitor the running status in real time. If a light alarm occurs, the l-al appears on the LED monitor. ■ Programming mode : This mode allows you to configure function code data and check a variety of

information relating to the inverter status and maintenance. ■ Alarm mode : If an alarm condition arises, the inverter automatically enters Alarm mode. In

this mode, you can view the corresponding alarm code* and its related information on the LED monitor. * Alarm code: Indicates the cause of the alarm condition. For details, refer to Chapter 2,

Section 2.8 "Protective Functions" and Section 7.4.7 "Reading alarm information" in this Chapter.

Figure 7.3 shows the status transition of the inverter between these three operation modes. If the inverter is turned ON, it automatically enters Running mode, making it possible to start or stop the motor.

*1 A value exceeding 9999 cannot be displayed as is on the 4-digit LED monitor screen, so the LED monitor displays one-tenth of the actual value with the x10 LED lit.

*2 When the LED monitor displays an output voltage, the 7-segment letter u in the lowest digit stands for the unit of the voltage "V."

*3 These PID related items appear only when the inverter drives the motor under the PID process control specified by function code J01 (= 1, 2 or 3).

*4 When the LED monitor displays a PID command or its output amount, the dot (decimal point) attached to the lowest digit of the 7-segment letter blinks.

*5 When the LED monitor displays a PID feedback amount, the dot (decimal point) attached to the lowest digit of the 7-segment letter lights.

input terminals by any of function codes E61 to E63 (= 20). *9 A torque current value appears only when the vector control is selected (F42 = 6).

Function code E42 (LED display filter) allows you to filter the monitoring signals for the monitor items such as output frequency and output current. Increase the E42 data if the monitored values are unstable and unreadable due to fluctuation of load.

7.3.2 Monitoring light alarms The FRENIC-MEGA identifies abnormal states in two categories--Heavy alarm and Light alarm. If the former occurs, the inverter immediately trips; if the latter occurs, the inverter shows the l-al on the LED monitor and blinks the KEYPAD CONTROL LED but it continues to run without tripping.

Which abnormal states are categorized as a light alarm ("Light alarm" object) should be defined with function codes H81 and H82 beforehand.

Assigning the LALM signal to any one of the digital output terminals with any of function codes E20 to E24 and E27 (= 98) enables the inverter to output the LALM signal on that terminal upon occurrence of a light alarm.

For details of the light alarm objects, refer to Chapter 2, Section 2.8 "Protective Functions."

■ How to check a light alarm factor

If a light alarm occurs, l-al appears on the LED monitor. To check the current light alarm factor, enter Programming mode by pressing the key and select 5_36 on Menu #5 "Maintenance Information."

It is also possible to check the factors of the last three light alarms 5_37 (last) to 5_39 (3rd last).

For details of the menu transition of the maintenance information, refer to Section 7.4.6 "Reading maintenance information."

■ How to reset a light alarm

After checking the current light alarm factor, to switch the LED monitor from the l-al indication state back to the running status display (e.g., output frequency), press the key in Running mode.

If the light alarm factor has been removed, the KEYPAD CONTROL LED stops blinking and the LALM signal turns OFF. If not (e.g. DC fan lock), the KEYPAD CONTROL LED continues blinking and the LALM signal remains ON.

7.3.3 Setting up frequency and PID commands You can set up the desired frequency and PID commands by using and keys on the keypad. It is also possible to set up the frequency command as load shaft speed, motor speed or speed (%) by setting function code E48.

■ Setting up a frequency command Using the keypad (F01 = 0 (factory default) or 8)

(1) Set function code F01 to "0" or "8." This can be done only when the inverter is in Running mode.

(2) Press the / key to display the current reference frequency. The lowest digit will blink.

(3) To change the reference frequency, press the / key again. To save the new setting into the inverter's memory, press the key (when E64 = 1 (factory default)). When the power is turned ON next time, the new setting will be used as an initial reference frequency.

• In addition to the saving with the key described above, auto-saving is also available

(when E64 = 0). • If you have set function code F01 to "0" or "8" but have selected a frequency command

source other than frequency command 1 (i.e., frequency command 2, frequency command via communication, or multi-frequency command), then the and keysare disabled to change the current frequency command even in Running mode. Pressing either of these keys just displays the current reference frequency.

• When you start specifying the reference frequency or any other parameter with the / key, the least significant digit on the display blinks; that is, the cursor lies in the least

significant digit. Holding down the / key changes data in the least significant digit and generates a carry, while the cursor remains in the least significant digit.

• After the least significant digit blinks by pressing the / key, holding down the key for more than 1 second moves the cursor from the least significant digit to the most significant digit. Further holding it down moves the cursor to the next lower digit. This cursor movement allows you to easily move the cursor to the desired digit and change the data in higher digits.

• Setting F01 data to "8" enables the balanceless-bumpless switching. When the frequency command source is switched to the keypad from any other source, the inverter inherits the current frequency that has applied before switching, providing smooth switching and shockless running.

Using analog input (F01 = 1 to 3, or 5) • Applying the gain and bias to analog inputs (voltage inputs to terminals [12] and [V2], and current

input to terminal [C1]) enables the frequency to be set within an arbitrary range (frequency vs. analog input level).

(Refer to the description of F18.) • Noise reduction filters are applicable to these analog inputs. (Refer to the descriptions of C33, C38 and C43.) • The normal/inverse operation for the frequency command 1 setting (F01) can be selected with

function code C53 and be switched between them with the terminal command IVS assigned to any of the digital input terminals.

(Refer to the descriptions of E01 through E09.)

7-10

• To input bipolar analog voltage (0 to ±10 VDC) to terminals [12] and [V2], set C35 and

C45 data to "0." Setting C35 and C45 data to "1" enables the voltage range from 0 to +10 VDC and interprets the negative polarity input from 0 to -10 VDC as 0 V.

• A reference frequency can be specified not only with the frequency (Hz) but also with other menu items, depending on the setting of function code E48 (= 3 to 5, or 7).

■ Settings under PID process control To enable the PID process control, you need to set the J01 data to "1" or "2." Under the PID control, the items that can be specified or checked with and keys are different from those under regular frequency control, depending upon the current LED monitor setting. If the LED monitor is set to the speed monitor (E43 = 0), you can access manual speed commands (frequency command) with and keys; if it is set to any other, you can access the PID process command with those keys.

Setting the PID process command with and keys (1) Set function code J02 to "0: / keys on keypad." (2) Set the LED monitor to something other than the speed monitor (E43=0) when the inverter is in

Running mode. When the keypad is in Programming or Alarm mode, you cannot modify the PID process command with the / key. To enable the PID process command to be modified with the / key, first switch to Running mode.

(3) Press the / key to display the PID process command. The lowest digit and its decimal point blinks on the LED monitor.

(4) To change the PID process command, press the / key again. The PID process command you have specified will be automatically saved into the inverter’s internal memory. It is retained even if you temporarily switch to another PID process command source and then go back to the via-keypad PID process command. Also, it is retained in the memory even while the inverter is powered off, and will be used as the initial PID process command next time the inverter is powered on.

• Even if multi-frequency is selected as a PID process command (SS4 or SS8 = ON), you

still can set the process command using the keypad. • When function code J02 is set to any value other than "0," pressing the / key

displays, on the 7-segment LED monitor, the PID process command currently selected, while you cannot change the setting.

• On the 7-segment LED monitor, the decimal point of the lowest digit is used to characterize what is displayed. The decimal point of the lowest digit blinks when a PID process command is displayed; the decimal point lights when a PID feedback amount is displayed.

■ Settings under PID dancer control To enable the PID dancer control, you need to set the J01 data to "3." Under the PID control, the items that can be specified or checked with and keys are different from those under the regular frequency control, depending upon the current LED monitor setting. If the LED monitor is set to the speed monitor (E43 = 0), the item accessible is the primary frequency command; if it is set to any other data, it is the PID dancer position command.

Setting the PID dancer position command with the and keys (1) Set the J02 data to "0: / keys on keypad." (2) Set the LED monitor to something other than the speed monitor (E43=0) when the inverter is in

Running mode. When the keypad is in Programming or Alarm mode, you cannot modify the PID command with the / key. To enable the PID dancer position command to be modified with the / key, first switch to Running mode.

(3) Press the / key to display the PID dancer position command. The lowest digit blinks on the LED monitor.

(4) To change the command, press the / key again. The command you have specified will be automatically saved into the inverter’s internal memory as function code J57 data. It is retained even if you temporarily switch to another PID command source and then go back to the via-keypad PID command. Furthermore, you can directly configure the command with function code J57.

• Even if multi-frequency is selected as a PID command (SS4 or SS8 = ON), you still can

set the PID dancer position command using the keypad. • When the J02 data is set to any value other than "0," pressing the / key displays, on

the 7-segment LED monitor, the PID command currently selected, while you cannot change the setting.

• On the 7-segment LED monitor, the decimal point of the lowest digit is used to discriminate the PID related data from the reference command. The decimal point blinks or lights when a PID command or PID feedback amount is displayed, respectively.

7.3.6 Remote and local modes The inverter is available in either remote or local mode. In the remote mode that applies to ordinary operation, the inverter is driven under the control of the data settings stored in the inverter, whereas in the local mode that applies to maintenance operation, it is separated from the control system and is driven manually under the control of the keypad.

• Remote mode: Run and frequency commands are selected by function codes or source switching signals except "Select local (keypad) operation" LOC.

• Local mode: The command source is the keypad, regardless of the settings specified by function codes. The keypad takes precedence over the settings specified by communications link operation signals.

Run commands from the keypad in local mode The table below shows the input procedures of run commands from the keypad in the local mode.

When Data for F02 (run command) is : Input Procedures of Run Commands from Keypad

0: Enable / keys on keypad (Motor rotational direction from

digital terminals [FWD]/[REV])

Pressing the key runs the motor in the direction specified by command FWD or REV assigned to terminal [FWD] or [REV], respectively. Pressing the key stops the motor.

1: Enable terminal command FWD/REV

2: Enable / keys on keypad (Forward)

Pressing the key runs the motor in the forward direction only. Pressing the key stops the motor.

No specification of the motor rotational direction is required.

3: Enable / keys on keypad (Reverse)

Pressing the key runs the motor in the reverse direction only. Pressing the key stops the motor.

No specification of the motor rotational direction is required.

Switching between remote and local modes The remote and local modes can be switched by a digital input signal provided from the outside of the inverter.

To enable the switching, you need to assign LOC as a digital input signal to any of terminals [X1] to [X9] by setting "35" to any of E01 to E09, E98 and E99.

Switching from remote to local mode automatically inherits the frequency settings used in remote mode. If the motor is running at the time of the switching from remote to local, the run command will be automatically turned ON so that all the necessary data settings will be carried over. If, however, there is a discrepancy between the settings used in remote mode and ones made on the keypad (e.g., switching from the reverse rotation in remote mode to the forward rotation only in local mode), the inverter automatically stops.

The transition paths between remote and local modes depend on the current mode and the value (ON/OFF) of LOC, as shown in the status transition diagram given below. Also, refer to above table for details

Transition between Remote and Local Modes by LOC

7.3.7 External run/frequency command By factory default, run and frequency commands are sourced from the keypad. This section provides other external command source samples--an external potentiometer (variable resistor) as a frequency command source and external run switches as run forward/reverse command sources.

Set up those external sources using the following procedure.

(1) Configure the function codes as listed below.

Function code

Name Data Factory default

f 01 Frequency command 1 1: Analog voltage input to terminal [12] 0

f 02 Operation method 1: External digital input signal 2

e 98 Terminal [FWD] function 98: Run forward command FWD 98

e 99 Terminal [REV] function 99: Run reverse command REV 99

If terminal [FWD] and [REV] are ON, the F02 data cannot be changed. First turn those terminals OFF and then change the F02 data.

(2) Wire the potentiometer to terminals across [13], [12], and [11].

(3) Connect the run forward switch between terminals [FWD] and [CM] and the run reverse switch between [REV] and [CM].

(4) To start running the inverter, rotate the potentiometer to give a voltage to terminal [12] and then turn the run forward or reverse switch ON (short-circuit).

For precautions in wiring, refer to Chapter 2 "SPECIFICATIONS."

Basic key operation This section gives a description of the basic key operation in "Quick Setup," following the example of the function code data changing procedure shown in Figure 7.6. This example shows you how to change function code F01 data (Frequency command source) from the factory default " / keys on keypad (F01 = 0)" to "Current input to terminal [C1] (C1 function) (4 to 20 mA DC) (F01 = 2)." (1) Turn the inverter ON. It automatically enters Running mode. In that mode, press the key to

switch to Programming mode. The function selection menu appears. (In this example, *fn: is displayed.)

(2) If anything other than *fn: is displayed, use the and keys to display *fn:.

(3) Press the key to proceed to the list of function codes.

(4) Use the and keys to display the desired function code (f 01 in this example), then press the key. The data of this function code appears. (In this example, data 0 of f 01 appears.)

(5) Change the function code data using the and keys. (In this example, press the key two times to change data 0 to 2.)

(6) Press the key to establish the function code data. The saue appears and the data will be saved in the memory inside the inverter. The display will return to the function code list, then move to the next function code. (In this example, f 02.)

Pressing the key instead of the key cancels the change made to the data. The data reverts to the previous value, the display returns to the function code list, and the original function code reappears.

(7) Press the key to return to the menu from the function code list.

Cursor movement You can move the cursor when changing function code data by holding down the key for 1 second or longer in the same way as with the frequency settings. This action is called "Cursor movement."

It is possible to change or add function code items subject to quick setup. For details, consult your Fuji Electric representatives.

7.4.2 Setting up function codes -- Menu #1 "Data Setting" -- Menu #1 "Data Setting" (!f__ through!y__) in Programming mode allows you to set up all function codes. To set function codes in this menu, it is necessary to set function code E52 to "0" (Function code data editing mode) or "2" (Full-menu mode).
