Product Description:

The PY2C015U0XXXC03 is a servo amplifier from the PY Super BL Servo Amplifiers series manufactured by Sanyo Denki. It acts as the power interface between a motion controller and a brushless servo motor. The amplifier converts low-level velocity or torque commands into the regulated current required for precision positioning and speed regulation in industrial automation lines.

The unit can deliver a continuous output of 15 A, establishing the maximum motor phase current available for steady-state operation. A current-limit input centered at ±2.0 VDC allows the controller to cap drive current without changing the fundamental gain settings. For feedback, the built-in current monitor provides 0.5 V ±20% per rated current, allowing actual phase current to be observed with a voltmeter. The internal loop bandwidth extends to 400 Hz, indicating how rapidly the amplifier can react to command changes before attenuation occurs. Speed control spans a ratio of 1:5000, so the same drive can execute slow homing moves and high-speed traverses without changing the mechanical gearing.

Speed stability under varying loads remains within ±0.1% of maximum rotational speed, supporting repeatable throughput on machines with cyclic inertia changes. The aluminum chassis weighs 1.5 kg, which simplifies mounting on lightweight panels and limits vibrational mass. Reliable operation is maintained at ambient temperatures up to 55 °C when cabinet airflow is adequate. The torque command port accepts a high-impedance 10 kΩ reference, minimizing the load on upstream analog outputs. The velocity command channel has the same impedance, but it is not used in torque mode. Across an ambient temperature range of 0 to 55 °C, temperature-related speed drift remains within ±0.5% of maximum rotational speed. Supply-line variations introduce a speed deviation of only ±0.1%. An auxiliary monitor provides 0.5 V ±20% per 1,000 rpm for real-time velocity measurement.
