Monitoring Safe Halt
Indramat · CLM01.3-M Flying Cutoff Control
What does F501 mean?
The safety function Safe Halt is selected, but the drive interlock is not active, or the control has given the drive enable. This indicates a discrepancy in the safety circuit state, where the drive is enabled despite Safe Halt being active or the interlock being open.
Common Causes
- Error in the actuation of the drive interlock (Indramat DIAX04 SSE-03VRS: connector X3).
- Malfunction of the control system, sending an incorrect drive enable signal.
Repair Steps & Checklist
Click steps to track your progress.
- 1
De-energize the system. Inspect the wiring of the drive interlock circuit, specifically at the Indramat DIAX04 SSE-03VRS connector X3, for loose connections, damage, or incorrect termination.
- 2
Verify the state of the drive interlock inputs to the Indramat DIAX04 SSE-03VRS drive controller using diagnostic tools or status indicators, ensuring they reflect the expected safety state (e.g., inactive when Safe Halt is selected).
- 3
Check the status of the drive enable signal from the control system. Ensure that the control is not commanding drive enable while Safe Halt is active.
- 4
Consult the control system's diagnostics and event logs for any errors or unexpected commands related to drive enable or safety functions.
- 5
If the issue persists and appears to originate from the control system's logic or hardware, contact the control system manufacturer for further assistance.
