SI CU: Brake Control Error
Siemens · DAsl Diagnostics and Alarms
What does F01630 mean?
The drive-integrated 'Safety Integrated' function on the Control Unit (CU) has detected an error in the brake control, initiating a STOP A. Causes include incorrect parameter p1278, wire breakage, no brake connected, a ground fault in the brake cable, or a short-circuit in the brake winding. This fault prevents safe operation and indicates a critical issue with the holding brake system that must be resolved.
Complete Troubleshooting Guide
- 1
Check parameter p1278 for correct setting according to the brake type and application.
- 2
Verify the brake connection for wire breakage, proper continuity, and absence of ground faults.
- 3
If the brake is not releasing, check if it releases with p1278=1 and p9602/p9802=0 (SBC de-activated) to isolate wiring issues.
- 4
Inspect the brake winding for short-circuits. Replace the brake if a short is detected.
- 5
Ensure the motor cable is correctly shielded to prevent EMC issues that could affect brake control.
