Yaskawa SGDH-02AE-OY 200V AC Servo Drive (Sigma II Series)

The Yaskawa SGDH-02AE-OY is a compact AC servo drive belonging to the renowned Sigma II family. Rated for 200V input (single-phase or three-phase), this drive provides precise control for small to medium power servo motors. Its high-speed processing and advanced tuning algorithms ensure stable operation in demanding motion control applications, including pick-and-place robots, CNC rotary tables, printing presses, and automated inspection machines.

Core Technical Parameters

• Rated Output Current: 1.6A continuous, 4.8A peak

• Input Voltage: Single-phase/Three-phase 200-230V AC ±10%, 50/60Hz

• Control Methods: IGBT PWM sine wave current control

• Feedback: 13-bit incremental encoder (2048 PPR) or 17-bit absolute encoder option

• Maximum Speed: 5000 rpm (with corresponding SGMPH-02A motor)

Precision Control Modes

The SGDH-02AE-OY supports three primary control modes: position, speed, and torque. In position mode, it accepts step/direction, CW/CCW pulse trains up to 500 kHz, with electronic gear ratio programmable from 1/100 to 100. Positioning completion signal is output within ±1 encoder pulse. Speed mode offers a 1:5000 speed range with ±0.01% regulation. Torque mode provides linear output for tension control. Mode switching can be performed via external digital inputs or serial commands.

Advanced Autotuning

The drive features real-time autotuning that automatically adjusts position and speed loop gains based on load inertia estimation. It can suppress mechanical resonance using two notch filters (50 Hz to 2000 Hz, programmable depth up to -40 dB). Adaptive vibration suppression reduces settling time for long-stroke or low-rigidity mechanisms. The tuning results are stored in non-volatile memory and can be transferred to a PLC for replication across multiple axes.

PLC Connectivity and I/O

The SGDH-02AE-OY is designed for straightforward integration with PLCs, particularly Omron CJ, CS, and CP series via high-speed pulse outputs or analog modules. The drive provides: 7 digital inputs (24V DC, 4mA) for servo-on, alarm clear, gain select, and forward/reverse drive prohibit; 4 digital outputs (open-collector, 30V/50mA) for ready, alarm, positioning complete, and speed coincidence; 2 analog monitor outputs (±10V) for speed and torque feedback signals. A built-in RS-232/RS-422 interface supports Yaskawa's standard protocol and Modbus, enabling full parameter access from a PLC.

Safety and Protection Functions

The SGDH-02AE-OY includes comprehensive protection: overcurrent (instantaneous and time-delayed), overvoltage (DC bus > 400V), undervoltage (< 150V), overload (electronic thermal), regenerative error, encoder disconnection, and overspeed. It also features dynamic braking with an internal regenerative resistor (30W, 40Ω) and provision for external resistor for high-inertia applications. The drive meets safety standard EN 61800-5-1 with STO (Safe Torque Off) ready hardware.

Physical Dimensions and Installation

Dimensions: 130mm (H) × 60mm (W) × 130mm (D) without heatsink. Weight 0.8 kg. Mounting is by M4 screws through a DIN rail adapter or direct backplate. Ambient operating temperature: 0°C to 55°C (derate above 45°C at 2.5%/°C). Humidity: 20–90% non-condensing. Vibration resistance: 5.9 m/s² at 10–55 Hz. Enclosure rating IP10 (open type), requires installation in a clean, ventilated cabinet.

Typical System Configuration

A complete motion system includes the SGDH-02AE-OY drive paired with a Yaskawa SGMPH-02A (200W, 0.64 Nm rated torque) or SGMGH-02A (low inertia) servo motor, a compatible PLC (e.g., Omron CP1H with pulse output), and a 24V DC power supply for I/O. For multi-axis systems, the drive can be networked via an optional JUSP-NS115 DeviceNet or Profibus module.

Reliability and Standards

MTBF is rated at 150,000 hours at 40°C ambient. The drive complies with UL 508C, cUL, CE (EMC Directive 2014/30/EU, Low Voltage Directive 2014/35/EU), and RoHS. The SGDH series is known for its ruggedness and long service life in industrial environments.

Conclusion

The Yaskawa SGDH-02AE-OY 200V servo drive offers precision, reliability, and easy PLC integration. Its advanced autotuning, compact size, and wide protection coverage make it an excellent choice for OEMs and system integrators requiring high-performance motion control.
