IE3 motors have different motor characteristics from IE1 and other motors. Set the parameters as specified by the motor characteristics. If you have a momentary power loss, and the drive detects oC [Overcurrent] or ov [Overvoltage] during speed search after it restores power, set these parameters:

  • b3-03 [Speed Search Deceleration Time] = default value × 2

  • L2-03 [Minimum Baseblock Time] = default value × 2

  • L2-04 [Powerloss V/f Recovery Ramp Time] = default value × 2
