Motor phase W missing

Danfoss · VLT Micro Drive FC 51

What does 32 mean?

One of the motor output phases (Phase W) is detected as missing by the drive. This usually points to a disconnected motor cable, a broken wire, or a poor connection at either the drive or motor terminals, preventing proper motor operation.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Using a multimeter, verify continuity of the phase W cable from the drive's output terminal to the motor's terminal.

  2. 4

    Ensure the motor is not severely overloaded, which could lead to intermittent connections or high resistance at terminals over time.
