Safety
- Refer to Siemens documentation
- Ensure qualified technician performs repairs
Causes and Fixes
- 1
Wait for Test Completion
Allow the system to complete the automatic servo testing sequence. This typically takes 30-90 seconds depending on the number of configured axes.
Monitor the diagnosis buffer (Menu > Diagnostics > Service > Diagnosis) to track test progress
- 2
Verify All Axes Complete Testing
Check that all configured servo axes in MD30100 (axis assignment) complete their individual test sequences without generating additional alarms.
Do not attempt to move axes manually during this testing phase
- 3
Confirm System Ready State
Once testing completes, verify the control displays 'Ready' status and all axis enable signals are active in the machine status display.
Call a technician if:
- ·Testing fails to complete after 5 minutes
- ·Additional servo alarms appear during testing
- ·System fails to reach Ready state after test completion
Prevention
- Allow adequate time for system startup
- Avoid parameter changes during production
- Maintain clean power supply to prevent restart cycles
Common Mistakes
- Interrupting the test sequence by cycling power
- Attempting axis movement during testing
- Modifying parameters while testing is active
