Drive1 and Drive2 Motor Rotation
If careful attention to phase rotation is not made during connection of the panel to the three-phase power
supply and motor, then there is only a one chance in four that the motor will rotate correctly in both drive1
and drive2 modes.
The other three possibilities and the corresponding corrective actions are as follows:
Problem:
Motor turns correctly in Drive2 mode and incorrectly in Drive1 mode.
Solution:
Swap the leads at the drive’s output terminals.
Problem:
Motor turns correctly in Drive1 mode and incorrectly in Drive2 mode.
Solution:
Swap the leads at the drive’s output terminals.
Problem:
Motor turns incorrectly in both modes.
Solution:
Swap the leads at the motor leads on the contactor's output terminals.
