Chapter 4 Explanation of Functions
4.2.4 Frequency source setting
A001: Frequency source setting
Related code
The frequency source setting function allows you to select the method to
input the frequency-setting command.
Motor rotation direction is inverted when -10 to 0V is given as frequency
command to 02-L terminals.
Item Function code Data Description
(00)
(Valid only when the OPE-SR is used)
Use the control provided on the digital operator to set the frequency.
01
Input the frequency-setting command via a control circuit terminal (0-L,
OI-L, or O2-L).
02
Use the digital operator (function "F001") or remote operator to set the
frequency.
03
Input the frequency-setting command via an RS485 communication
terminal.
04
Input the frequency-setting command from the board connected to
optional port 1.
05
Input the frequency-setting command from the board connected to
optional port 2.
06
Use the SJ-FB to input the frequency-setting command as a pulse train
(see 4.2.21)
07
Use the SET-Freq command of the easy sequence function as the
frequency-setting command.

Use the operation result of the set frequency operation function as the
frequency-setting command. (see 4.2.12)
4.2.5 Run command source setting
A002: Run command source setting
C001 to C008: Terminal [1] to [8] functions
C019: Terminal [FW] active state
F004: Keypad Run key routing
Related code
The run command source setting function allows you to select the
method to input operation commands (to start and stop the motor).
As the operation commands via control circuit terminals, turn the
FW signal (for forward operation) or RV signal (for reverse
operation) on and off to start and stop the motor, respectively.
(Note that the factory setting assigns the FW signal to intelligent input terminal [8].)
To switch each intelligent input terminal between a and b contacts, specify each terminal with function
"C011" to "C019", and then perform input a/b (NO/NC) selection for each terminal.
When using the digital operation for the inverter operation, specify the desired motor operation direction
with function "F004", and use the RUN and STOP/RESET keys to start and stop the motor, respectively.
If the start commands for both forward and reverse operations are input at the same time, the inverter will
assume the input of a stop command.
Item Function code Data Description
01
Input the start and stop commands via control circuit
terminals (FW and RV).
02
Input the start and stop commands from the digital or
remote operator.
03
Input the start and stop commands via RS485
communication terminals.
04 Input the start and stop commands from option board 1.

05 Input the start and stop commands from option board 2.

C011 to C018 01 b (NC) contact
Note 1: If function "31" (forcible operation) or "51" (forcible-operation terminal) is assigned to an intelligent
input terminal, the settings made with functions "A001" and "A002" will be invalidated when the
said intelligent input terminal is turned on and those methods to input frequency-setting and
operation commands which are specified for the said terminal will be enabled.
Note 2: On the remote operator (SRW) being used to operate the inverter, pressing the REMT (remote)
key enables you to input both frequency-setting and operation commands from the remote
operator.
