2. Direction of movement of the encoder is incorrect.
3. Incorrect polarity of the motor.
4. Axis mechanically blocked.
5. Brake applied.
6. Axis is in endstop position.
Remedy:
1. Check mechanically whether the motor can be moved.
2. Check the encoder. Invert the direction of movement of the encoder,
if necessary.
3. Check motor connection to the controller.
4. Release mechanical blocking.
5. Check brake and control signals. The brake must be released
