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).

Valid for inputs:
C_05
Required settings: A_02 = 01 (terminal control)
A_02 = 02 (keypad control)
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.
L100-M Series inverters can also use [FW] and [RV] inputs in real time to determine the
direction of rotation for the keypad Run key. This requires setting A_02=02 (keypad
control) and Run Key Routing F_04 = 02 (terminal). The operation is shown below.
