Product Description:

The PY2A030A3MF1P01 servo amplifier is produced by Sanyo Denki as part of the PY Super BL Servo Amplifiers series. It conditions mains power and modulates output current to drive matched servo motors, acting as the core power stage in position-controlled axes. In industrial automation, the unit links a motion controller to the motor, supplies regulated energy, and executes braking functions that help machinery operate accurately and safely.

Rated for an output capacity of 30 A, the amplifier supplies the current needed for rapid acceleration. It connects to 200 VAC utility lines and uses a single-phase main circuit, avoiding three-phase feeders in small machines. Input fusing must handle an inrush current of 23 A, while continuous power demand reaches 2.0 kVA. The logic circuits and gate drivers draw only 40 VA, so a small control transformer is adequate. Command data arrive through a position-control interface that supports incremental moves and absolute positioning. Because the regenerative resistor is not built in, excess energy from frequent stops must be diverted to an external braking resistor. The unit has a depth of 135 mm, allowing it to align with standard enclosure rails.

During energization, the control section experiences a surge of 40 A, which is separate from the main-circuit inrush current. When motion stops, the dynamic brake engages after a 10 ms delay and can absorb 360 J per event, helping prevent overvoltage trips on the DC bus. Feedback from an encoder with a resolution of 2000 P/R allows the amplifier to refine position error during each control-loop cycle for smooth contouring. The housing is 168 mm high and has a mass of 2.0 kg, allowing the amplifier to be mounted beside other compact drives. The external regenerative resistor can be sized for the braking demands of the application without adding its heat directly to the amplifier housing.
