Product Description:
The PY2A015E0XXXPT0 belongs to the PY Super BL Servo Amplifiers series manufactured by Sanyo Denki. It is a pulse-train-driven servo amplifier intended for closed-loop velocity and position control of Super BL AC servo motors in general industrial automation. By converting high-speed step or direction pulses from a motion controller into proportional three-phase drive currents, the unit regulates motor torque and speed using internal feedback.
The amplifier can deliver up to 15 A of continuous output, which is the maximum steady-state phase current available to the connected motor windings. During command changes, the control section withstands a surge current of 40 A; this margin helps prevent drive trips when large error corrections are requested. Small-signal behavior is characterized by a bandwidth of 400 Hz, allowing accurate tracking of rapid velocity commands without excessive overshoot. The pulse input accepts edge rates as high as 2 million pulses per second, so high-resolution motion controllers and high-speed indexers can command motion without frequency division. A velocity control range of 1:5000 allows the amplifier to regulate motor speed from the base speed down to 0.02% of that speed without losing stability, supporting rapid traverse and slow creep modes. Line regulation remains within ±0.1%, load regulation remains within ±0.1%, and temperature drift is limited to ±0.5%, helping maintain repeatable performance as operating conditions change.
Leakage current does not exceed 0.5 mA, which helps the installation meet applicable ground-fault limits. At power-up, the main bus draws a surge of 23 A, so the upstream circuit protection must tolerate this inrush current. The velocity monitor terminal provides an output of 0.5 V ±20%, offering an analog signal for oscilloscope measurements or PLC diagnostics. With a mass of 1.5 kg, the amplifier can be mounted on a control panel without adding substantial weight. A regenerative processing circuit and the built-in dynamic brake dissipate excess kinetic energy returned by the motor during deceleration.
