Product Description:

The PY0A050A0GG1P01 is a servo amplifier produced by Sanyo Denki for the PY Super BL Servo Amplifiers series. Designed for use with brushless servo motors, it converts three-phase mains power into precisely modulated current so that motion controllers can execute accurate positioning tasks in automated machinery. By regulating motor torque and speed in closed-loop operation, the unit supports assembly stations, pick-and-place axes, and other equipment that require fast, repeatable movements.

The drive can deliver up to 50 A of output current, giving it headroom for acceleration without saturation. A frequency response of 400 Hz keeps phase lag low, allowing tight gain settings in high-bandwidth position loops. Its power section is rated for 200 VAC operation on a three-phase supply, and an interface dedicated to position control accepts pulse or analog commands from the host controller. Velocity can be adjusted across a 1:5000 range, enabling stable performance from creep speeds to rapid traverses. A built-in dynamic brake clamps the motor when commanded to stop, shortening deceleration time without external hardware. The current monitor outputs 2.0 V ±20%, while the velocity monitor supplies 2.0 V ±10%, providing real-time feedback for drive tuning and diagnostics.

A feedback sensor resolution of 2000 P/R works with the amplifier’s internal counters to provide smooth interpolation at slow speeds. During overruns, excess energy is routed to a regeneration circuit that can absorb 60 W through a 20 Ω resistor, preventing the DC bus voltage from rising excessively. The chassis weighs 4.4 kg, making panel mounting manageable inside compact enclosures. It requires 50 mm of clearance above and below the chassis to maintain adequate airflow around the amplifier and remove heat from the power section.
