Product Description:

​Part of the PY Super BL Servo Amplifiers assembly line, this Sanyo Denki designed PY0A050A model type has a three-phase, input power (main circuit) rating of 200-230VAC +10%, -15%, 50/60Hz ±3Hz. It provides constant operation within specified limits of the input voltage. Through parameter switching, it offers velocity, torque or position control to meet distinct application requirements. The device is intended for operation in environments with temperature ranging from 32°F to 131°F (0°C to 55°C) and continues to provide reliable operation in this broad temperature spectrum.

Moisture-related problems are safeguarded and its operating and storage humidity is capped to a maximum of 90% RH without condensation. With a mass of 2.7 kg, the part PY0A050A is lightweight to facilitate easier handling and installation. It incorporates a built-in dynamic brake for emergency stopping, enhancing safety during critical operations. The velocity control range spans 1:5000 and that offers precise speed adjustments to suit diverse application needs. Additionally, it features regenerative processing with an optional resistor which allows for energy recovery during deceleration phases. The absolute position output signal operates at 9600 bps (start-stop synchronization) or 1/2 Mbps (Manchester method) shows accurate position feedback for precise control.

Protection functions include overcurrent, overload, amplifier overheating, over-speed, low main circuit voltage, sensor error, and CPU error, collectively ensuring robust protection against potential operational hazards.​ Beyond these specifications, the PY0A050A servo amplifier also features a cooling fan motor and is designed to maintain optimal internal temperatures during operation, thereby extending the amplifier's lifespan and ensuring consistent performance. This feature is particularly beneficial in environments where maintaining specific temperature conditions is critical for system reliability.​
