The Sigma II platform represents Yaskawa's established technology for servo motion control, combining robust hardware design with flexible configuration options to accommodate diverse application requirements.
Power and Electrical Specifications
The SGDH-04AE-OY operates on a single-phase AC input voltage of 200 to 230 V at 50/60 Hz, with a maximum applicable motor capacity of 0.4 kW. The output power rating is 400 watts, providing sufficient power for a wide range of small to medium-duty motion applications. The output voltage is three-phase 0 to 230 V AC, with an output current of 2.8 A. The drive is engineered for efficiency, delivering reliable performance while maintaining compact dimensions suitable for panel integration.
The servo amplifier includes built-in circuits for overcurrent protection, overvoltage protection, undervoltage protection, overload protection, and overtemperature protection, ensuring safe operation under normal and abnormal conditions. The unit is designed with attention to thermal management, dissipating heat effectively during sustained operation at rated output.
Communication and Control Interface
The SGDH-04AE-OY features MECHATROLINK-II communications interface, supporting high-speed real-time command transmission between the servo drive and motion controller. This communication protocol enables coordinated multi-axis motion control with deterministic timing essential for synchronized operations such as electronic gearing, cam profiling, and interpolation. The MECHATROLINK-II command type interface supports both position control and velocity control modes, with flexible command configuration for application-specific requirements.
The drive is compatible with Yaskawa's Sigma II series of servo motors, including the SGMAH series (3000 r/min) and other Sigma II motor families. The serial encoder interface supports 16-bit relative positioning or higher resolution absolute encoding depending on motor model, providing accurate feedback for closed-loop position and velocity control. The drive accepts command inputs from a motion controller or PLC and returns actual position, velocity, and torque data for monitoring and closed-loop regulation.
Application and Compatibility
The SGDH-04AE-OY is suitable for applications including pick-and-place machines, labeling equipment, small conveyor systems, packaging machinery, printing presses, and light assembly automation. The drive's 400W power rating is ideal for applications requiring moderate torque output with high precision and responsiveness. The Sigma II amplifier can be paired with various motor frame sizes offering different inertia characteristics to optimize performance for specific load conditions.
For multi-axis systems, multiple SGDH Series drives can be connected on a shared MECHATROLINK-II network, enabling coordinated motion control across up to 30 axes from a single motion controller. The drive supports standard control modes including position control, speed control, and torque control, selectable through software configuration to match application requirements. The interface accommodates both analog command inputs for legacy systems and digital communications for modern network-based architectures.
Configuration and Setup
Configuration of the SGDH-04AE-OY is accomplished through parameter settings accessible via the front-panel operator interface or through the MECHATROLINK-II network. Parameters adjust control gains, filter settings, acceleration and deceleration profiles, and protection thresholds to optimize performance for specific load characteristics. The drive supports autotuning functions that automatically adjust control parameters based on measured motor and load behavior, reducing setup time for complex applications.
The servo amplifier includes status indicators for power, base block, alarm conditions, and communication activity, providing immediate visual feedback on drive status. Diagnostic capabilities include alarm history logging for troubleshooting and maintenance planning. The SGDH-04AE-OY conforms to industry standards for electrical safety and electromagnetic compatibility, suitable for integration into CE-marked and UL-certified equipment.
In combination with compatible Sigma II servo motors, the SGDH-04AE-OY delivers smooth motion with minimal torque ripple, enabling high-quality production output in precision manufacturing environments. The drive's proven reliability and flexible configuration options make it a trusted choice for machine builders and system integrators requiring dependable motion control solutions.
