• 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 Cn. 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
