It is a mode to control motors turned on with the same PID output frequency.
The picture below shows that the priority is “Motor1 (M1)

Motor2 (M2)
 Motor3 (M3)”.
(The priority can be changed automatically according to operating time).

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). In addition, Aux Motor with the next priority of Main Motor is turned on
and the new operating Aux Motor becomes Main Motor. Operating motors can be controlled
together by PID. It is possible to check the priority in [AP1-45/46 Aux Priority].
A condition that Aux Motor is turned off.
If the real operating frequency of Main Motor is lower than the frequency set in Stop Freq,
AP1-44(Aux Motor Run) decreases(-1) after the time set in AP1-54(Aux Stop DT) and the
present Main Motor becomes Aux Motor, decelerating based on time of [DRV-04 Dec Time]
until 0Hz.
At the same time, the rest of operating motors last PID control. It is possible to check the
priority in [AP1-45/46 Aux Priority].
