Yaskawa SGDH-10DE-OY Servo Driver

The Yaskawa SGDH-10DE-OY is a high-performance servo driver (amplifier) from the SGDH series, designed to drive AC servo motors in industrial automation systems. Rated for 400 V AC input and 1 kW output power, this driver provides precise control of torque, speed, and position for demanding motion control applications such as robotics, CNC machinery, packaging lines, and material handling equipment. The SGDH series is renowned for its reliability, advanced tuning algorithms, and comprehensive protection features.

This driver integrates with a wide range of Yaskawa servo motors and supports various feedback devices, including incremental and absolute encoders. It features a built-in dynamic brake, regenerative resistor connections, and multiple control modes (position, speed, torque, or combined). The SGDH-10DE-OY includes a front panel with LED indicators for status and error codes, and a connector for parameter setup via a digital operator or PC software. Its modular design allows easy mounting in standard control cabinets.

Installation and Wiring Guidelines

Mount the driver vertically on a panel, maintaining recommended clearances for airflow. Connect the three-phase mains to the L1, L2, L3 terminals and the motor to U, V, W. The control signals (enable, pulse train, analogue references) are connected via a 50-pin D-sub connector. Use shielded cables for all control and feedback signals to minimise noise. The regenerative resistor, if external, is connected to the B1, B2 terminals. Ensure the ground terminal is connected to the panel earth with low impedance. Parameter configuration is performed using the digital operator or the SigmaWin+ software.

Environmental and Compliance

The SGDH-10DE-OY complies with EN 61800-5-1 (safety), EN 61800-3 (EMC), and carries CE and UL marks. It is RoHS compliant and designed for pollution degree 2 environments, with an IP20 enclosure rating for installation in control cabinets.

Conclusion

The Yaskawa SGDH-10DE-OY servo driver delivers reliable, high-precision motion control for a wide range of industrial applications. Its robust design, advanced tuning features, and flexible connectivity make it a trusted choice for system integrators and machine builders seeking performance and durability.
