Yaskawa SGDH-05AE Sigma II Servo Amplifier

The Yaskawa SGDH-05AE is a 0.5 kW AC servo amplifier in the Sigma II series, engineered for precision motion control across industrial automation systems. It accepts 200-230 VAC three-phase input at 50-60 Hz and delivers 0-230 V AC output at up to 3.8 A, enabling torque, speed, or position control with exceptional accuracy. The amplifier features serial encoder technology for automatic recognition of Sigma II servomotors, adaptive tuning with 10 levels of rigidity, and machine resonance suppression. Speed control spans 1:5000 with ±0.01% variance at rated speed across 0-100% load, ±0.1% variance across 0-55°C ambient, and 0% variance within ±10% supply voltage deviation. Peak torque reaches 300% of nominal for 3 seconds. Torque control reproducibility is ±2%. The unit supports analog control for speed and torque, pulse-train positioning, and optional network connectivity via Mechatrolink I/II, DeviceNet, or Profibus. SigmaWin and SigmaWin Plus software enable real-time torque, speed, and command monitoring, with FFT and machine simulation capabilities in the Professional version. Forced-air cooling maintains operation across 0-55°C ambient. A built-in keypad and serial port simplify commissioning and parameter adjustment. Soft-start acceleration and deceleration are independently programmable from 0-10 seconds.
