Common troubleshooting methods for Siemens servo motor maintenance

Shanghai Quli Automation Technology Co., Ltd.: Siemens CNC system servo motor maintenance is a complex technical service industry. In recent years, servo motors have been used more and more widely, and the use of the market in Chinese Mainland has increased rapidly. The demand for technical services such as spindle motor maintenance has become increasingly urgent. Due to the fact that most of the servo motors used in China are imported products with high technological content, foreign servo motor manufacturers have adopted non-standard encoders or installation methods in order to monopolize the maintenance service market, making spindle motor maintenance more difficult and forming servo motor maintenance as an outstanding technical skill.
Professional maintenance of various brands of servo motors for repair faults: magnet explosion, magnet detachment, stuck rotation, encoder wear, code disk/glass disk wear and tear, motor overheating, motor water ingress, motor abnormal operation, high-speed operation noise, loud noise, brake failure, brake pad wear, low-speed normal high-speed deviation, high-speed normal low-speed deviation, start alarm, start trip, overload, overvoltage, overcurrent, unable to start, weak start, operation shaking, demagnetization, running position, walking deviation, output imbalance, encoder alarm, encoder damage, inaccurate position, alarm when powered on, tripping when powered on, driver server alarm code, burnt coil winding, aviation plug damage, incorrect origin position, encoder debugging/zero adjustment.

Common troubleshooting methods for Siemens servo motor maintenance

　　Siemens servo motor maintenanceIt is a common problem encountered in daily life. A servo motor refers to an engine that controls the operation of mechanical components in a servo system, and is an indirect variable speed device that supplements the motor. This motor can achieve very accurate control speed and position accuracy, and can convert voltage signals into torque and speed to drive the controlled object. Compared with single machine asynchronous motors, servo motors have three significant characteristics: high starting torque, wide operating range, and no self rotation phenomenon.

Siemens servo motor maintenanceWhat are the common faults? What is the solution?
1、 Motor overcurrent and overload alarm
Improper installation of the motor and excessive mechanical load can cause overload alarms.
Solution: Install correctly to reduce mechanical load;
2. The motor is flooded with water. The insulation of the motor stator coil to ground is less than 10M Ω, and the power socket is short circuited between phases.
Solution: The insulation resistance of the cleaned and dried stator should be greater than 100M Ω. If it does not meet the requirements, replace the power socket or motor stator as needed;
2、 Motor overheating alarm (430 alarm)
1. Encoder detection error. Solution: Replace the encoder with a new one. Can be completed by users and on-site maintenance engineers;
2. Temperature sensor detection error, temperature sensor damaged. The normal value should be between 55-80k Ω, and the resistance value varies with the ambient temperature. Solution: Send the motor back to the company for repair;
Improper installation of the motor and excessive mechanical load can cause overheating alarms. The solution should be correctly installed to reduce mechanical loads;
4. The brake coil of the motor with brake is short circuited or open circuited. The brake is not opened, causing excessive load on the motor. The reason is due to inaccurate voltage capacity provided to the brake coil. The brake cannot be fully appliedOpen it. Solution: Replace the brake and equip it with an independent power supply. The resistance of the alpha series motor brake coil is about 230 Ω, and the coil voltage is 90V. The resistance of the α i series motor brake coil is 26 Ω, and the coil voltage is 24V.
Alright, the above is the introduction to the maintenance of Siemens servo motors.
