Servo Drive

Description

The Yaskawa SGDM-15DN is an AC servo amplifier of the Sigma-II series for 400 V servo applications in the power range up to 1.5 kW. The SGDM series is technically based on the SGDH platform, meaning that alarms and troubleshooting are fully compatible with the SGDH series. The device is designed for precise axis control, high dynamics, and reliable continuous operation in industrial automation environments.

Repair Description

Input check: Visual inspection, measurement of mains and DC link voltage, short-circuit test on U/V/W
Disassembly & Cleaning: Opening the housing, cleaning the boards, checking the cooling surfaces
Analysis: Checking the power stage, capacitors, current measurement, and control logic
Repair: Replacement of defective power components and aged components
Testing & Load Test: Test run with reference motor, monitoring current and temperature
Long-term Test & Completion: Continuous operation under load, documentation of measurement results
