Product Description:

The PY2C030U0XXXC06 is a servo amplifier produced by Sanyo Denki for the PY Super BL Servo Amplifiers series. It receives analog velocity or torque references from a motion controller and modulates the motor phases so that the commanded speed is reached quickly and maintained accurately. Used in positioning tables, pick-and-place arms, and other industrial axes, the amplifier forms the power stage of a closed-loop drive system by regulating motor current and monitoring actual shaft velocity.

The power section is rated for 30 A, allowing it to energize medium-frame servo motors while remaining within its current capacity. A command range of ±2.0 VDC lets the controller request motoring or regenerative braking with symmetrical resolution. Input sensitivity is matched to control electronics by an impedance of 10 kΩ, minimizing the load placed on the upstream digital-to-analog converter. The velocity loop bandwidth reaches 400 Hz, so speed changes follow reference updates with minimal phase lag. Across that bandwidth, the amplifier maintains a velocity control ratio of 1:5000, enabling precise low-speed indexing as well as full-speed travel. Current feedback is presented at 0.5 V ± 20% when the phase current reaches 100%. A separate velocity monitor provides 0.5 V ± 20% at 1,000 rpm, simplifying real-time diagnostics.

The housing weighs 2.0 kg and can be mounted in multi-axis cabinets without placing excessive load on the panel. Continuous operation is permitted from 0 to 55 °C, while storage is permitted from -20 °C to 65 °C. The amplifier can operate at altitudes up to 1,000 m and in ambient humidity up to 90% RH, allowing installation on most factory floors. Frequency-compensated regulators hold the output within a load variation of ±0.1% as mechanical inertia or friction changes. When the line supply shifts, voltage variation remains limited to ±0.1%, ensuring that the velocity loop receives stable power throughout the machine’s operating cycle.
