Note
•
Power on Run and Speed Search - If the speed search is not enabled, the inverter will
start its operation in a normal V/F pattern and accelerate the motor. A fault may be
triggered if the inverter starts operating while the load is still rotating. To prevent faults
with Power-on Run, enable speed search. Set CON-71, bit 4 to 1. The inverter will perform a
speed search at the beginning of the operation.
•
If Power On Run is left disabled and the inverter powers up with an active run
command, it will not start. The digital input (run command) must be first deactivated, and then
reapplied 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.
