Product Description:

The PY0A050A1FC1P01 servo amplifier is manufactured by Sanyo Denki within the PY Super BL Servo Amplifiers series. It is an AC power stage that conditions mains energy and supplies controlled current to brushless servomotors operating under position commands from a motion controller. Used in automated assembly cells and material-handling equipment, the amplifier closes the drive loop by cooperating with an incremental feedback sensor and the host PLC to hold position, manage acceleration, and limit overshoot during fast directional changes.

The power section is rated for a continuous output of 50 A and is fed from a 200 V AC supply on a single-phase line. When the control logic is enabled, the circuitry momentarily draws a control inrush current of 40 A, while the main charging network reaches 18 A during capacitor energization. Internal drive bandwidth is tuned to 400 Hz, allowing tight velocity and position regulation at high update rates. A built-in dynamic brake dissipates kinetic energy, and regenerative processing is also integrated so surplus energy is returned to the DC bus rather than sent to the brake resistor whenever possible. The amplifier uses a position-control interface, and a velocity monitor terminal outputs 2.0 V ±10% so external equipment can track speed in real time.

The dynamic brake can absorb up to 1800 J of energy before additional protection is required for the bus capacitors. It engages fully after a delay of 24.0 ms, coordinating with machine safety sequencing. Speed regulation spans a ratio of 1:5000, enabling slow jogs as well as rapid indexing under the same parameter set. Feedback is provided by a wiring-saving incremental sensor with a resolution of 2000 P/R, giving the controller fine spatial resolution without requiring extra cabling. The unit has an overall mass of 4.4 kg, which simplifies cabinet layout while keeping vibration loading low.
