Overview
- The Yaskawa SGDB-05VD is a compact, reliable servo amplifier of the Σ-Series. It belongs to the 200V class and is suitable for axes up to 0.45 kW. This version has a standardized analog/compatible command interface (D-Interface). The SGDB-05VD is typically used in CNC machines, handling modules, and automation systems where precise and stable control is required.
- Device category: AC Servo Amplifier (Servopack)
- Series/Class: SGDB (200V class)
- Design: robust, fan-supported, service-friendly
Model Designation
- (based on the official SGDB model code table)
- SGDB = Σ-Series Servopack
- 05 = Power size 0.5 kW (0.45 kW effective according to nameplate)
- V = Supply 200 V (Region/Variant identification)
- D = Command Interface Type: Standard command interface
- (In contrast to 'N' = MECHATROLINK)
- Options (empty suffix) = no additional options installed

Service Notes
- Regularly clean fans and cooling slots
- Preventively check/replace power electronics (IGBTs, capacitors) after years of operation
- Consistently implement cable shielding
- Ensure low-resistance grounding
- Back up parameters and restore them after repair
- Do not perform Megger measurements across encoder/interface lines
Repair Description
- Incoming inspection: Visual check, insulation measurement motor path, DC bus measurement, function test without motor
- Disassembly & Cleaning: Open device, remove dust/oil, renew thermal pads
- Analysis: Check control board (SGDB-CAVD), test IGBT module, measure optocouplers, rectifier, capacitors
- Repair: Replace defective components, resolder thermally stressed areas, preventively renew capacitors/fans
- Testing & Load Test: Test with reference motor 0.45–0.6 kW, monitoring current, temperature, DC ripple, and alarm behavior
- Long-term Test & Conclusion: Continuous operation test, complete documentation of the repair and measurement protocols
