Possible Solutions and Tips
- Replace the motor as a test.
- Check cable connections.
- Disconnect the motor from the shaft or belt and test at different speeds.
- Check or replace the drive.
- Perform an insulation test 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 error is usually due to a faulty encoder or worn-out bearings.

Possible Solutions and Tips
- Disconnect the motor from the shaft or belt and test at different speeds.
- Disconnect the motor connection cables and completely relieve the motor of loads. Then turn it by hand.
If the motor is still stiff or makes unusual noises, the bearings may be defective.
- Check the motor insulation and windings for breakdown.
- Check the encoder.
