Motor Contactor delay times
The drive can set a delay for the time taken to close the motor contactor. It is important as if the motor contactors are open the drive could be damaged.
The time in P3-01 should be set long enough for the motor contactor to safely close.

Sets a delay time between a Direction signal being applied to the drive and the drive energising the motor, this ensures that the motor contactor has had enough time to change state before current flows from the drive to the motor.
Typical values are 0.2 to 0.5 seconds.
During the delay time the drive will display “CC” to indicate Contactor Closing time.
