Servo Drive

Description

The Yaskawa SGDM-01AD is a compact AC servo amplifier of the Sigma-II generation for low-power drives. It is technically based on the SGDH platform, which is why alarms and troubleshooting of the SGDH series are fully compatible. The device is proven in continuous operation and is frequently used in compact CNC axes, handling systems, and special machines.

Service Notes

Save parameters before service
Regularly check encoder and motor cables
Keep ventilation openings clean
No insulation measurement (Megger) when installed
In case of encoder errors, always check cable and shielding

Repair Description

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