The drive measures ripples in DC bus voltage to detect input phase loss.

The drive detects phase loss when power supply phase loss occurs or the main circuit capacitor becomes unusable, which causes PF [Input Phase Loss] to show on the keypad.

Disable the detection of the input power supply phase loss function in these conditions:

  • During deceleration

  • The run command is not input

  • The output current is less than 30% of the drive rated current.
