Forward Run/Stop and Reverse Run/Stop Commands:
When you input the Run command via the terminal [FW], the inverter executes the Forward
Run command (high) or Stop command (low). When you input the Run command via the
terminal [RV], the inverter executes the Reverse Run command (high) or Stop command
(low).

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.
Example (default input configuration shown see
page 66):
See I/O specs on page 21,22.
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 Run command
is not active.
