Product Description:

The PY0A050E0XXYP00 is a servo amplifier manufactured by Sanyo Denki for the PY Super BL Servo Amplifiers series. Designed for closed-loop motion systems, the module converts DC bus energy into three-phase drive currents that accelerate, decelerate, and hold brushless servo motors with millisecond responsiveness. It mounts inside a control cabinet and interfaces with upstream position controllers through standard analog or pulse references, forming the power stage that converts low-level commands into motor torque in industrial automation lines.

During continuous operation, the amplifier can supply a phase current of 50 A, enabling high-torque acceleration for medium-frame motors. At power-up, the control circuitry tolerates a surge current of 40 A, while the mains input side experiences a separate inrush current of 18 A; both values guide breaker sizing and cable selection. The integrated dynamic brake closes 24.0 ms after a stop command and safely absorbs up to 1800 J of kinetic energy, helping prevent overspeed. For extended deceleration, the unit routes excess energy to an external resistor bank rated at 1500 W with a resistance of 20 Ω. The internal resistor handles 60 W during brief events, covering normal indexing moves.

For velocity regulation, the current loop supports a frequency response of 400 Hz, allowing tight tracking of command profiles without noticeable phase lag. Speed can be trimmed from the base speed down to 0.02% of the rated speed, providing a velocity control range of 1:5000. Real-time verification is available through two monitor outputs: the current monitor produces 2.0 V with a tolerance of ±20% in proportion to phase current, while the velocity monitor supplies 2.0 V with a tolerance of ±10% in relation to motor speed. The amplifier’s aluminum chassis weighs 4.4 kg, allowing installation in densely packed panels without overloading DIN rails or slide-out racks.
