Product Description:

The PY2A030A2GS1PK0 servo amplifier is manufactured by Sanyo Denki for the PY Super BL Servo Amplifiers series. The unit conditions line power, processes position commands, and regulates current to a matched brushless motor. In industrial automation, it serves as the power stage for axes that demand tight positioning accuracy, such as gantry loaders or inspection tables. Its position-control interface accepts feedback from an incremental encoder and transmits error-corrected torque commands, allowing the motion controller to achieve repeatable moves with low settling times.

The rated output capacity is 30 A, so the amplifier can deliver this continuous phase current to the motor windings without derating. The power section operates from a 200 VAC supply and limits mains inrush current to 23 A, while a separate control circuit momentarily draws 40 A during startup. Thermal management is handled by a forced-air cooling system that moves heat away from the semiconductor bridge. Closed-loop bandwidth reaches 400 Hz, enabling accurate tracking of high-frequency position commands. Because the unit is supplied without a built-in regenerative resistor, surplus energy must be dissipated by an external braking element.

The built-in dynamic brake engages automatically, and its energy sink is rated for 360 J per event, allowing controlled deceleration of moderate-inertia loads. Position feedback is expected from an incremental encoder with a resolution of 2000 P/R; this matches the internal counter hardware and supports fine interpolation. The speed loop remains linear across a 1:5000 velocity span, providing consistent regulation from crawl speed to maximum speed. Input conductors connect to a three-phase mains block, and leakage current with a 2 m motor cable is limited to 0.5 mA to satisfy grounding requirements. The assembly weighs 2.0 kg, so it can be mounted on lightweight DIN-rail panels without additional supports.
