SH2 status test to inactive
Heidenhain · NC Control
What does 10593 E011 mean?
The measured status of the '-SH2' signal is at a 'low' level and fails to change to the 'inactive' ('high' level) status, even though the CC (Controller Control) is triggering its corresponding watchdog. This points to an internal software error or hardware defect.
Common Causes
- The measured status of the "-SH2" signal is "low" level.
- The "-SH2" signal does not change to the "inactive" ("high" level) status, although the CC is triggering the corresponding watchdog.
- Internal software error.
- Hardware defective.
Repair Steps & Checklist
Click steps to track your progress.
- 1
Power cycle the NC control and related CC modules to reset the system and clear transient software errors.
- 2
Inspect the wiring and connections of the -SH2 signal path, particularly where it interfaces with the CC unit, for damage or loose terminals.
- 3
Check the CC module for any visible signs of damage, overheating, or component failure.
- 4
Verify the safety software configuration related to the -SH2 signal and its interaction with the CC watchdog.
- 5
If possible, use a multimeter or oscilloscope to monitor the -SH2 signal level during startup and operation to identify its state transitions.
