Product Description:
The PY0A150A0R62S02 servo amplifier is produced by Sanyo Denki for the PY Super BL Servo Amplifiers series. Designed for machine tools, robotics, and material-handling axes, the module supplies controlled three-phase power to matched brushless motors, enabling precise velocity regulation and rapid deceleration within automated cells. It includes a dynamic brake and acts as the interface between the motion controller’s speed commands and the motor windings, ensuring stable torque production across a wide operating range.
The power stage can deliver a continuous phase current of 150 A, allowing it to support motors with substantial sustained torque demands without exceeding its continuous current limit. Its main circuit has an apparent power rating of 8.4 kVA and draws power from a three-phase mains supply while limiting inrush current to 30 A. A frequency response of 400 Hz supports tight speed regulation and allows the amplifier to react quickly to changing motion commands. The internal power section uses 200 VAC switching devices to regulate the voltage and current supplied to the connected motor. Auxiliary electronics require only 40 VA of control power, simplifying cabinet power distribution. After a stop request, the dynamic brake engages within 24.0 ms to absorb energy generated during deceleration.
During sudden stops, the brake resistor can dissipate up to 2450 J per event, helping prevent excessive voltage on the DC link. The velocity control algorithm covers a speed range of 1:5000, allowing the same amplifier to manage low-speed movement and high-speed travel without changing gains. Resolver or encoder feedback with a resolution of 6000 P/R is supported, providing accurate position data to the controller. The amplifier has a mass of 8.5 kg, which must be considered when selecting cabinet mounting hardware and support structures. Its total heat loss is 260 W, an important factor when determining enclosure airflow and cooling capacity. The control inrush current is 40 A and should be considered when selecting circuit protection for the auxiliary supply.
