Product Description:
The PY0A050A0GGBP01 is a servo amplifier produced by Sanyo Denki for the PY Super BL Servo Amplifiers series. It interfaces between a motion controller and a brushless servo motor. The amplifier regulates current and voltage so that closed-loop position, velocity, and torque commands can be executed accurately on automated machinery. This control arrangement allows the connected motor to respond to changing motion commands while maintaining stable operation under varying loads.
The main output stage has an amplifier capacity of 50 A, allowing it to drive medium-frame servomotors without saturation. Incoming power must come from a three-phase source. The control loop has a frequency characteristic of 400 Hz, which supports rapid speed corrections during demanding motion cycles. Velocity can be adjusted across a wide 1:5000 control range, permitting slow indexing as well as full-speed movement from the same motor. A built-in dynamic brake engages within 24.0 ms after detecting a loss of power, helping dissipate regenerated energy and shorten the stopping distance. The control circuit has a 40 A inrush current, while the main circuit has an 18 A inrush current. The amplifier operates at elevations up to 1,000 m and in condensation-free environments with relative humidity levels up to 90%.
An internal braking resistor handles up to 60 W of continuous power dissipation and has a resistance of 20 Ω. Its electrical characteristics match the 1,800 J dynamic-brake energy budget while helping prevent excessive heat accumulation inside the cabinet. The housing weighs 4.4 kg, allowing the panel to support the unit without heavy structural reinforcement. The frame withstands mechanical shock levels of 2 G during transportation or seismic events. It also tolerates vibration levels up to 0.5 G, which supports installation on machinery subject to regular movement or moderate mechanical oscillation.
