SCF

Motor short-circuit

Schneider Electric · ATV32HD11N4 Variable Speed Drive

What does SCF mean?

A short-circuit or grounding fault has occurred at the drive output, or significant ground leakage current is detected (especially with multiple motors). This indicates a severe electrical fault in the motor or its cabling, risking immediate damage to the drive and motor.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Reduce the switching frequency of the drive (if applicable and safe for the application) to mitigate leakage current.

  2. 4

    Connect chokes in series with the motor if multiple motors are connected or ground leakage is persistent.
