Servo Drive Repair

Servo drive repair services specialize in diagnosing and restoring precision motor control systems used in robotics, CNC machines, packaging equipment, and other automated processes. A servo drive controls the torque, speed, and position of a servo motor based on command signals, making it vital for high-precision operations. Common issues that require repair include feedback loop errors, encoder failures, blown fuses, power supply problems, IGBT or MOSFET damage, and software or firmware faults.

The repair process typically involves a detailed inspection, testing with specialized diagnostic tools, replacement of damaged components, reprogramming, and closed-loop testing under load. Experienced technicians also verify communication protocols (such as EtherCAT or CANopen) and ensure alignment between the drive and motor encoder. Proper servo drive repair helps maintain tight motion control, reduces production downtime, and extends the life of expensive automation systems. Preventive maintenance and timely repairs can also prevent cascading failures in servo systems.
