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 following:
• 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.
• 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.
The inverter can store up to 16 different fixed target frequencies (speeds) in parameters A020
to A035. Binary inputs select the speed through four of the intelligent terminals configured as
binary-encoded inputs CF1 to CF4 per the table. These can be any of the eight inputs, and in
any order. You can use fewer inputs if you need eight or fewer speeds.
