Mechanical brake low

What does 63 mean?
The actual motor current failed to exceed the configured release brake current within the specified start delay time window. This indicates an issue with the mechanical brake's release mechanism, potentially due to a stuck brake, insufficient current to release it, or incorrect timing settings, preventing the motor from starting.
Complete Troubleshooting Guide
- 1
Check the mechanical brake for any physical obstructions or signs of sticking.
- 2
Verify that the release brake current setting is appropriate for the brake used.
- 3
Adjust the start delay time window if necessary to allow sufficient time for the brake to release.
- 4
Measure the motor current during attempted brake release to confirm it reaches the set threshold.
