Saturation Trip

Vacon · NX All-in-One Application

What does 7 mean?

This fault indicates an internal issue such as a defective component or a short-circuit/overload in the brake resistor circuit. If accompanied by Fault 1 (Overcurrent), it suggests a problem with the motor cable or the motor itself, leading to saturation conditions within the drive's output stage.

Common Causes

  • The magnetic flux in the motor core has reached saturation levels.
  • Over-excitation of the motor causing magnetic saturation.
  • Incorrect motor control parameters leading to saturation.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Immediately switch off all power to the drive.

  2. 2

    If Fault 7 occurs concurrently with Fault 1 (Overcurrent), inspect the motor cables for damage or short circuits.

  3. 3

    If Fault 7 occurs concurrently with Fault 1, inspect the motor for insulation issues or internal damage.
