Product Description:

The PY0A150A0R62S03 servo amplifier is produced by Sanyo Denki within the PY Super BL Servo Amplifiers series. Designed to interface between a motion controller and a brushless servo motor, the unit converts command signals into regulated three-phase power while monitoring motor feedback. In automated assembly lines, packaging machinery, and semiconductor tools, the amplifier maintains precise velocity and torque so the mechanical axis follows programmed motion profiles without excessive overshoot.

During energization, the control circuitry momentarily draws an inrush current of 40 A, while the main power circuit has a separate inrush current of 30 A. After the DC link stabilizes, carrier modulation sustains an output frequency of up to 400 Hz, allowing the connected motor to reach high operating speeds. A built-in brake transistor routes kinetic energy to the braking circuit after a programmed delay of 24.0 ms, helping prevent load rebound during a stop. Closed-loop velocity control operates across a speed range of 1:5000. Within that range, the speed error remains within ±0.1% through line and load regulation, while internal thermal compensation limits ambient temperature drift to ±0.5%.

The amplifier directs regenerative energy through an external shunt port rated for 4500 W. For regenerative energy within the normal operating duty, an onboard resistor with a resistance of 6.7 Ω dissipates up to 120 W without exceeding its thermal limit. The cast-aluminum chassis weighs 8.5 kg, so cabinet shelves must support its static load while maintaining adequate airflow around the housing. Operation is permitted at altitudes up to 1000 m and at relative humidity levels up to 90%, making the unit suitable for common factory conditions. The regenerative circuit supports frequent acceleration, deceleration, and direction changes by limiting excess voltage in the DC bus during dynamic operation.
