A condition that extra Aux Motor is turned on .
After a real operating frequency reaches the frequency set in Start Freq belonging to the next
priority number and the time set in AP1-53(Aux Start DT) passes, AP1-44(Aux Motor Run) increases
(+1) and it becomes Aux Motor, accelerating based on time of [DRV-03 Acc Time]/[DRV-04 Dec
Time] until [AP1-60 Follower Freq].
At the same time, as an inverter corresponding to the next priority is turned on, the motor becomes
Main Motor(available PID control). It is possible to check the priority in [AP1-45/46 Aux Priority].
A condition that Aux Motor is turned off.
