Yaskawa Robot Servo Motor Failure Alarm Maintenance
Yaskawa Robot Servo Motor Failure Alarm Maintenance
Common faults of Yaskawa robot servo motor repair:
1. Motor encoder failure: the encoder code disc is broken and worn, and the encoder origin is lost;
2.Common faults of the motor: the motor rotor is magnetized, the bearing is stuck and does not rotate, the motor coil is burned out by leakage, the overcurrent and overvoltage motor heats up, the motor starts to report ** trip, the motor rotor loses magnetization (demagnetization), The motor is running weak, the motor brake fails, the brake of the motor with brake cannot be opened, the brake of the motor with brake is noisy, the brake of the motor with brake is stuck and cannot rotate, the motor bearing is too loud, buzzing, and the body is hot and noise Too large, the motor rotor is disconnected and concentrically bent, the motor position is not correct, the origin is out of order, the output is unbalanced, the motor is running badly, the motor loses magnetization and maintenance fails, the brake disc is burned out, and the servo motor can be used for a while The alarm will be shut down (power off) and restarted after time. The motor will be energized but cannot start, the motor flange is broken, the motor shaft end is broken, the motor shaft end is worn, the keyway is broken, etc.
