Product Description:

The PY0A100A0R42S01 is a servo amplifier produced by Sanyo Denki for the PY Super BL Servo Amplifiers series. It conditions three-phase mains power and delivers controlled current to a matched brushless servo motor, enabling accurate speed and torque regulation in automated conveyors, pick-and-place heads, and packaging lines. By integrating dynamic braking hardware and regenerative energy handling, the module helps maintain quick deceleration profiles while keeping cabinet space and wiring complexity minimal.

The drive stage is rated for 100 A, so the motor terminals can receive peak line current suitable for large-inertia loads. It accepts a 200 VAC supply on a three-phase main circuit. That section draws an inrush current of 20 A at power-up, while the control circuit briefly draws 40 A through its dedicated input. Frequency response extends to 400 Hz, allowing the amplifier to track high-bandwidth velocity commands received through a ±2.0 VDC speed reference. A separate current-limit pin uses the same ±2.0 VDC range and allows the controller to reduce torque in real time within a ±10% tolerance. Encoder feedback at 6,000 pulses per revolution is conditioned internally, and an analog velocity monitor reproduces the actual shaft speed at 2.0 V with ±10% accuracy. A built-in dynamic brake clamps the motor during emergency stops.

The amplifier dissipates up to 90 W through its internal resistor of 10 Ω, and an external resistor network can handle as much as 3,000 W when an application requires repeated fast deceleration. The velocity loop has a range of 1:5000, allowing the same motor to operate at a slow inspection speed or run at full throughput without retuning. At 6.0 kg, the chassis is suitable for panel mounting while providing adequate mass for heat dissipation. The internal and external resistor options allow braking energy to be managed according to the machine’s deceleration demands.
