SI CU: Brake Control Error

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.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 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.

2. 4

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

3. 5

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