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).

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

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.
