Product Description:
The PY0A030A1FH1P00 servo amplifier is produced by Sanyo Denki within the PY Super BL Servo Amplifiers series. Designed for compact motion axes, this power unit conditions 200-volt AC input and modulates motor current so that the amplifier can precisely close position loops. It serves as the intermediary between a drive PLC and an incremental encoder-equipped servomotor, handling both velocity and torque regulation. This functionality supports industrial automation tasks that require tight position control and integrated dynamic braking.
At its output stage, the amplifier can deliver a continuous current of 30 A, which is sufficient for mid-frame Super BL servomotors. The main power section is rated for 200 VAC operation and accepts a single-phase supply, simplifying cabinet wiring where three-phase power is unavailable. A frequency response of 400 Hz keeps current loops responsive to rapid load changes, while a velocity control range of 1:5000 permits slow indexing and high-speed traverses from the same drive. Position control is the selectable interface mode, and it works with an incremental encoder that provides 2,000 pulses per revolution to close the feedback loop. The main-circuit inrush current peaks at 18 A when the DC bus is charged. The built-in dynamic brake engages automatically after motion stops.
Energy dissipated during emergency stops is limited to 360 J by the brake resistor, helping protect the amplifier from excessive regenerative energy. The brake circuit reacts within 6.5 ms to clamp the bus voltage after a stop command. During normal operation, the control section draws 40 VA and experiences a transient inrush current of 40 A when energized. The assembly weighs 2.2 kg, allowing installation in densely populated control cabinets without adding excessive panel load. Sensor signals are processed through the incremental encoder channel, enabling the amplifier to compare commanded motion with measured motor movement. Closed-loop tuning then corrects speed and position deviations during acceleration, steady operation, and deceleration.
