Take caution on any safety accidents when operating the inverter with Power-on Run
enabled as the motor will begin rotating as soon as the inverter starts up.
4.7 Reset and Restart
Reset and restart operations can be setup for inverter operation following a fault trip,
based on the terminal block operation command (if it is configured). When a fault trip
occurs, the inverter cuts off the output and the motor will free-run. Another fault trip
may be triggered if the inverter begins its operation while motor load is in a free-run
state.

• To prevent a repeat fault trip from occurring, set Cn.71 (speed search options) bit 2 to
1. The inverter will perform a speed search at the beginning of the operation.
• If the speed search is not enabled, the inverter will start its operation in a normal V/F
pattern and accelerate the motor. If the inverter has been turned on without ‘Reset and
Restart’ enabled, trips must be reset, then turn the terminal block command off and on
to begin the inverter’s operation.
