Symptoms
The drive has detected that the motor is operating in a stalled condition. The motor speed is significantly below the commanded speed while drawing high current.
Possible Causes
- Mechanical load is jammed or seized
- Motor is undersized for the application
- Excessive starting torque required
- Motor parameters are incorrectly set
Troubleshooting Steps
- Step 1: Check the mechanical load for jams or excessive friction
Load rotates freely without excessive resistance - Step 2: Verify motor parameters match the motor nameplate
Parameters are correct - Step 3: Check parameter 31.24 (stall function selection) and configure appropriately
Stall protection is configured for the application - Step 4: If the motor is genuinely undersized, upgrade to a larger motor and drive
New motor/drive handles the load without stalling
How to Reset
To reset: This is a warning - it does not require a reset. The warning clears automatically when the stall condition is resolved. If the drive trips, press RESET.
