HomeFrequently Asked Questions

Q
The motor casing temperature rose abnormally, far exceeding the normal operating range.
A
Overload operation, excessive load, poor cooling (such as fan failure), excessively high ambient temperature, or improper motor selection (insufficient torque).
Q
Servo motors with brakes cannot effectively maintain the load after power failure, causing them to slip or move.
A
This is typically caused by brake wear, incorrect brake voltage, or oil/grease contamination on the brake friction plate.
Q
If the motor makes abnormal noises or there is grease leakage at the shaft end, it may indicate that the motor is making abnormal noises or that there is grease leakage at the shaft end.
A
Possible reasons include bearing damage, incorrect installation alignment, or worn oil seals. Immediate inspection is recommended.
Q
Under bus-based control (such as CAN, EtherCAT) or pulse control, the motor loses synchronization with the host computer or commands are lost.
A
Check communication cables for electromagnetic interference, ensure correct termination resistors, and verify protocol settings.
Q
Even without any control commands input, the motor shaft continues to rotate slowly and uncontrollably.
A
This could be zero-drift in analog control, interference in the wiring, or a drive parameter configuration issue.
Q
The motor produces noticeable vibrations, whistling, or buzzing noises during operation.
A
Overload operation, excessive load, poor cooling (such as fan failure), excessively high ambient temperature, or improper motor selection (insufficient torque).
Q
The motor cannot accurately reach the commanded position, and the error accumulates over time or with the stroke.
A
Overload operation, excessive load, poor cooling (such as fan failure), excessively high ambient temperature, or improper motor selection (insufficient torque).
Q
The driver frequently triggers overload or overcurrent protection, causing the system to shut down.
A
Overload operation, excessive load, poor cooling (such as fan failure), excessively high ambient temperature, or improper motor selection (insufficient torque).
Q
The servo system may interfere with other electronic devices or be interfered with itself, leading to instability and false alarms.
A
Overload operation, excessive load, poor cooling (such as fan failure), excessively high ambient temperature, or improper motor selection (insufficient torque).
Q
The system alarmed "encoder error," indicating that the motor had lost position feedback and could not operate.
A
Overload operation, excessive load, poor cooling (such as fan failure), excessively high ambient temperature, or improper motor selection (insufficient torque).
