Possible Solutions and Tips
- Replace the motor for testing.
- Check cable connections.
- Remove the motor from the shaft or belt and test at various speeds.
- Check or replace the drive.
- Perform insulation testing on the motor.
- Visually inspect the motor.
- Visually inspect the encoder area for contamination, optionally have it cleaned by a specialized company.
- Check encoder signals: For older motors with analog encoders, read the sine diagrams with an oscilloscope.
For serial encoders, also check the operating voltages.
If these measures do not help, the fault is usually due to a faulty encoder or worn ball bearings.

Possible Solutions and Tips
- Remove the motor from the shaft or belt and test at various speeds.
- Disconnect the motor connection cables and completely free the motor from loads. Then turn it by hand.
If the motor is still stiff or makes unusual noises, the ball bearings may be defective.
- Check the motor for insulation and winding faults.
- Check the encoder.
