Brake fault

What does F268 mean?

The DIAX04 SSE-03VRS drive has detected an issue with the motor holding brake. This could be due to a wiring error, a faulty brake, incorrect brake control, or the brake not disengaging/engaging as expected. This fault prevents movement to ensure the load is securely held when stationary and to prevent accidental movement during operation.

• Motor holding brake wiring is open-circuited, short-circuited, or incorrectly connected to the DIAX04 SSE-03VRS drive.
• The motor holding brake itself is faulty (e.g., worn, coil damage, mechanical binding).
• Brake control parameters (e.g., brake release time, engage time) in the DIAX04 SSE-03VRS are incorrectly configured.
• Insufficient voltage or current supplied to the brake coil, preventing proper operation.
• Feedback signal from the brake (if available) indicates an unexpected state.

Click steps to track your progress.

1. 1

   Inspect the motor holding brake wiring from the DIAX04 SSE-03VRS drive to the motor for continuity, damage, or correct connections.

2. 2

   Verify the voltage and current supplied to the brake coil during release and engage commands. Compare to motor nameplate specifications.

3. 3

   Check the mechanical function of the brake: listen for engagement/disengagement, inspect for binding or excessive wear.

4. 4

   Review and adjust brake control parameters (e.g., S-0-0086, S-0-0087) in the DIAX04 SSE-03VRS for correct timing.

5. 5

   If the brake has an auxiliary switch, verify its wiring and function. If all checks pass, consider replacing the motor brake.
