Wiring Diagram
Conventions
The input wiring diagrams in this chapter are examples only. Default and non-default input
terminal assignments are noted throughout; your particular assignments may be different. The
wiring diagrams show the –xFU/–xFR model default [P24]–[PLC] jumper position (U.S./Jpn
versions), as shown below on the left. The common (return) for inputs is [CM1] in this case.
The diagram on the right shows the default jumper position and example input wiring for –xFE
models (Europe version). For this case, the common (return) for inputs is [P24]. Be sure the
jumper position and return terminal used match your application wiring needs.
Forward Run/
Stop and Reverse
Run/Stop
Commands
When you input the Run command via the dedicated terminal [FW], the inverter executes the
Forward Run command (high) or Stop command (low). When you input the Run command via
the programmable terminal [RV], the inverter executes the Reverse Run command (high) or
Stop command (low).
NOTE: The parameter F004, Keypad Run Key Routing, determines whether the single Run
key issues a Run FWD command or Run REV command. However, it has no effect on the [FW]
and [RV] input terminal operation.
WARNING: If the power is turned ON and the Run command is already active, the motor
starts rotation and is dangerous! Before turning power ON, confirm that the external Run
command is not active.

Code
Symbol Function Name State Description
FW Forward Run/Stop ON Inverter is in Run Mode, motor runs
forward
OFF Inverter is in Stop Mode, motor stops
01 RV Reverse Run/Stop ON Inverter is in Run Mode, motor runs
reverse
OFF Inverter is in Stop Mode, motor stops
Valid for
inputs:
C001, C002, C003, C004,
C005, C006, C007, C008
Required
settings:
A002 = 01
Notes:
When the Forward Run and Reverse Run
commands are active at the same time, the
inverter enters the Stop Mode.
When a terminal associated with either [FW]
or [RV] function is configured for normally
closed, the motor starts rotation when that
terminal is disconnected or otherwise has no
input voltage.
