Possible Solutions and Tips

• Test the motor by reconnecting it.
• Check cable connections.
• Run in jog mode without load.

If these actions do not help, the error is usually in the power stage of the drive module.

Possible Solutions and Tips

• Warm the device with an external source. If it turns on, this indicates a weak power supply that needs repair.
• Check fuses.
• Check the power supply of 3 x 200 or 220 volts depending on the model.

Possible Solutions and Tips

• Free the motor from the shaft or belt and test it at different speeds.
• Disconnect the motor connection cables and completely free the motor from load. Then turn it by hand.
  If the motor is still stiff or makes unusual noises, the ball bearings may be defective.
• Check motor insulation and windings for flashovers.
• Check the encoder.

Possible Solutions and Tips

• Visually inspect the encoder area for dirt, and if necessary, have it cleaned by a specialized company.
• Check encoder signals: For older motors with analog encoders, read sinusoidal diagrams with an oscilloscope.
  For serial encoders, check the operating voltages as well.
• Have the encoder replaced.
