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. 1

    Check parameter p1278 for correct setting according to the brake type and application.

  2. 2

    Verify the brake connection for wire breakage, proper continuity, and absence of ground faults.

  3. 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. 4

    Inspect the brake winding for short-circuits. Replace the brake if a short is detected.

  5. 5

    Ensure the motor cable is correctly shielded to prevent EMC issues that could affect brake control.
