4.8 Power-on Run
A power-on command can be setup to start an inverter operation after powering up, based on
terminal block operation commands (if they have been configured). To enable power-on run set
the drv (command source) code to 1(Fx/Rx-1) or 2 (Fx/Rx-2) in the DRV group.

• A fault trip may be triggered if the inverter starts operation while a motor’s load (fan-type load) is in
free-run state. To prevent this from happening, set bit4 to 1 in CON- 71 (speed search options) of the
Control group. The inverter will perform a speed search at the beginning of the operation.
• If the speed search is not enabled, the inverter will begin its operation in a normal V/F pattern and
accelerate the motor. If the inverter has been turned on without power-on run enabled, the terminal
block command must first be turned off, and then turned on again to begin the inverter’s operation.
Use caution when operating the inverter with Power-on Run enabled as the motor will begin rotating
when the inverter starts up.
