Verifying the Motor Rotation
This chapter is about a procedure to check the motor direction. Follow the instructions
below to protect the motor from rotating in the reverse direction.
•
Ensure that the motor, system, and any attached equipment are ready for start. It is the
responsibility of the user to ensure safe operation under any condition.
•
Failure to ensure that the motor, system, and any attached equipment are ready for
start could result in personal injury or equipment damage.
Note
•
Risk of damage to pumps/compressors can be caused by motor running in wrong
direction.
Before running the inverter, check the motor rotation.
Procedure of checking motor direction

Supply AC power input to the inverter. Take a look at keypad(LCD loader) and see if it
is turned on.
2 Set DRV-02 Keypad Run Direction code as
‘
