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).
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.
