SMODEX 90t
Symptoms
The crane reports a synchronization control fault. The dual-girder or multi-motor synchronization has lost coordination.
Possible Causes
- Motor speed mismatch between synchronized axes
- Encoder feedback inconsistency between motors
- Synchronization control parameter error
Troubleshooting Steps
- Step 1: Check motor speeds and encoder feedback on both axes
Speeds match within tolerance - Step 2: Verify the synchronization control parameters
Parameters are correctly set - Step 3: Test the synchronization function through a travel cycle
Axes move in sync
How to Reset
To reset: Restore synchronization, then clear the alarm.
