Causes and Fixes

1
Access MOD Function
Press MOD key and navigate to SYSTEM > CONFIGURATION to view current parameter status and any pending changes.
Look for asterisks (*) next to parameters indicating pending changes
2
Review Parameter Log
Check SYSTEM > DIAGNOSIS > PARAMETER LOG to identify which specific parameters were modified through TNCOPT.
Document all parameter changes before proceeding
3
Execute Controlled Restart
Perform END + 0 sequence to restart the control and activate the new parameter settings.
Ensure all programs are saved and machine is in safe position before restart

DIY Feasiblehigh confidence

Call a technician if:

·Parameter changes affect safety functions
·Servo instability after parameter modification
·Unable to identify which parameters were changed

Prevention

Always document parameter values before using TNCOPT
Create parameter backup files before optimization
Test parameter changes incrementally rather than all at once

Common Mistakes

Not restarting control after TNCOPT changes
Ignoring the alarm as informational only
Failing to verify critical safety parameters after optimization
