23

Broken Wire Detection (Adv. Code 0)

Vacon · X4 AC Drive

What does 23 mean?

This fault indicates an open circuit detected in the potentiometer wiring used for control. When the potentiometer circuit opens, the drive loses its reference signal, which can lead to the motor stopping, uncontrolled acceleration, or unpredictable behavior. This is a safety feature to prevent erratic operation.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Test the potentiometer for proper resistance change across its full range using a multimeter to ensure it is not internally open-circuited.

  2. 4

    Ensure that the potentiometer wiring is adequately shielded and separated from power wiring to prevent electrical noise interference.
