2.4.1 Troubleshooting for the motor operation and status

When the servo motor makes abnormal noises:
2
There is a source of vibration in
the connecting component.
The encoder is subject to
excessive vibration / shocks.
When the servo motor is overheating:
Mounting surface of the servo
motor has poor thermal
conductivity.

Possible cause
Check if there is any foreign
object, damage, or deformation
in the movable parts of the
connecting component.

3. Visually inspect the
Possible cause
Measure the temperatures of the
servo motor frame and the
mounting surface (metal). The
temperature difference should
not exceed 20°C (68°F).
Checking method

abnormal noises (disk
damage).
encoder's rear cover for dust
(encoder damage).
Checking method
Corrective action
Replace the connecting
component (such as the
coupling) or contact the
manufacturer.
Replace the servo motor.
Corrective action
Make sure the installation
surface is flat; if there are any
substance (such as paint,
gasket) between the mounting
surface and motor surface
resulting in poor heat
dissipation. Remove the
substance or use other methods
to help heat dissipation (such as
forced air cooling for the servo
motor).
