3. If the motor is rotating in the wrong direction, press the “STOP” key, remove power from the
drive, wait three minutes for the bus capacitors to discharge, and swap any two of the motor wires
connected to T1, T2, and T3 .
NOTE 1: The drive is phase insensitive with respect to incoming line voltage . Therefore, to change the
motor rotation, the phases must be swapped at the drive output terminals or at the motor .
NOTE 2: If the drive’s display is blank after power up, and it is a model equipped with heatsink fans, check
to make sure the fans are operating (they should be spinning anytime power is applied to the drive). If they
are not spinning, the drive’s display will be blank and the drive cannot be operated. If the fans are clogged
or jammed, disconnect power from the drive and remove any obstructions from the fans. Reapply power
to the drive and check the fans. If they are spinning, the drive’s display should appear and the drive should
operate properly . If there are no obstructions, the fan itself may be defective . Please contact the factory for
assistance .
