2.4.1 Troubleshooting for the Motor Operation and Status
Servo motor makes abnormal noise:
Possible causes
Checking methods
Handling measures
There is a source of
vibration in the
connecting component.
Check if there is foreign object,
damage, or deformation in the
movable parts of the connecting
component.
Replace the connecting
component (such as the
coupling) or contact the
manufacturer.
The encoder is
subjected to excessive
vibration / shocks.
1. Whether the servo motor has
been subjected to excessive force
or vibration, resulting in damage
to the encoder.
2. Remove and shake the encoder
for abnormal noise (disc damage).
3. Visually inspect the encoder's rear
cover for dust (encoder damage).
Replace the servo motor.
Servo motor overheating:
Possible causes
Checking methods
Handling measures
Mounting surface of
the servo motor has
poor thermal
conductivity.
Measure the temperatures of the
servo motor frame and the mounting
surface (metal). The temperature
difference should not exceed 20°C.
Check if the installation
surface is flat; if there are
other objects (such as
paint, gasket) between
the mounting surface and
motor surface, resulting
in poor heat dissipation.
Remove the object or use
other methods to help
dissipate heat (such as
forced air cooling for the
servo motor).
2.4.2 Servo Motor Mounting Directions and Precautions
The servo motor can be installed horizontally or vertically.
Installation direction
Precautions
Horizontal
If you are using a servo motor with oil seal, please refer to
the precaution measures in Section 2.4.5 for preventing oil /
water from entering the servo motor.
