Yaskawa SGDH-02AE-OY 200W AC Servo Amplifier for 200V Class

The Yaskawa SGDH-02AE-OY is a servo driver from the Sigma II series, delivering 200W rated output for 200V AC systems. This amplifier provides high-speed response, advanced autotuning, and integrated motion control features. It is designed to drive Yaskawa SGMAH or SGMGH series servomotors in precision applications.

Electrical Specifications

Main circuit input: 200-230V AC ±10%, single-phase or three-phase, 50/60Hz. Control power: same as main. Rated output current: 1.6A RMS. Peak current: 4.0A. Frequency response: 1.6 kHz. Built-in regenerative resistor (10W) handles deceleration energy. External regenerative resistor can be added for high inertia loads.

Control Modes and I/O

Supported modes: Position, Speed, Torque, and internal speed/torque. Digital inputs: 8 opto-isolated 24V DC (enable, alarm clear, gain select, etc.). Digital outputs: 5 open-collector (ready, alarm, positioning complete). Analog monitors: ±10V speed and torque output. Pulse train input (line driver or open collector) up to 500kHz from PLC positioning modules.

Communication and Tuning

RS-232C interface for connection to SigmaWin+ software. Automatic gain tuning in real-time, plus advanced vibration suppression filter. Parameter storage in EEPROM (non-volatile). Optional fieldbus modules: Profibus DP, DeviceNet, or MECHATROLINK-II. The driver also supports analog command input ±10V for speed/torque control from a PLC analog output.

Mechanical and Environmental

Dimensions: 60 x 160 x 170 mm (WxHxD). Weight: 1.2 kg. Mounting: DIN rail or direct screw. Operating temperature: 0-55°C, humidity 20-90% non-condensing. IP20 protection class. Cooling: natural convection (fanless). Vibration resistance: 5.9 m/s² (0.6G) at 10-55Hz.

Protection Functions

Overcurrent, overvoltage, undervoltage, overload, encoder failure, regenerative fault, and overspeed. LED display for fault code (7-segment). The driver automatically shuts down output in fault condition. Manual reset via input signal or power cycle. The internal watchdog timer ensures safe state in case of software hang.

PLC Integration

Position control via pulse train (CW/CCW or sign+pulse) allows direct interface to Omron, Siemens, or Mitsubishi PLC positioning modules. For analog speed control, a 0-10V signal from a PLC analog output sets motor speed. The driver outputs encoder position (A/B/Z differential signals) for PLC counting.

Applications

The SGDH-02AE-OY is used in small pick-and-place machines, electronic assembly, packaging equipment, and laboratory instruments. Its 200W capacity matches small servo motors driving light loads. The compact size fits control panels with limited space.

Compliance

CE, UL (file E147634), and RoHS certified. The driver meets EN 61800-3 for EMC and EN 61800-5-1 for safety. Suitable for industrial environments with pollution degree 2.

Conclusion

The Yaskawa SGDH-02AE-OY servo driver offers precise motion control for 200W motors. With multiple control modes and simple PLC connectivity, it remains a reliable choice for system retrofits and new designs.
