Mechanical Brake Status Mismatch
Vacon · NX Liquid-Cooled Drive
What does 58 mean?
The actual physical status of the mechanical brake (e.g., engaged or disengaged) does not correspond to the control signal issued by the drive. This discrepancy suggests either a mechanical failure of the brake, an issue with its wiring, or a problem with the drive's brake control output.
Common Causes
- Actual mechanical brake status does not match the commanded status.
- Brake activation or deactivation signal failure.
- Brake status feedback sensor fault.
