Product Description:

The PY0A030A0MABS00 servo amplifier is manufactured by Sanyo Denki and belongs to the PY Super BL Servo Amplifiers series. Acting as the interface between a motion controller and a brushless servo motor, the unit modulates three-phase power so that industrial equipment can execute precise velocity, torque, or position commands. By incorporating dynamic braking hardware, the amplifier supports production lines that require quick deceleration without external braking resistors.

A rated output of 30 A indicates the maximum continuous current that the drive can deliver to the motor windings. The control section draws 40 VA, allowing low-power logic supplies to energize the internal processors that implement velocity, torque, and position control. During startup, the circuitry tolerates a control inrush current of 40 A before settling into steady operation. The amplifier accepts a three-phase mains feed through its power unit, which is rated for 200 V AC with a dynamic brake; this arrangement supplies energy to the braking transistor without separate wiring. Closed-loop response has a bandwidth of 400 Hz, and commanded speed can be adjusted across a 1:5000 velocity range, enabling slow indexing and high-speed traverses in the same machine.

Power-on transients originating from the main supply are limited to 18 A, helping protect upstream fuses while the DC link charges. Excess kinetic energy returned from the motor is handled internally, and up to 20 W is dissipated through the built-in resistor network. This network presents an impedance of 50 Ω to the bus. The compact enclosure simplifies mechanical integration with a width of 50 mm, a maximum depth of 70 mm, and an overall height of 235 mm. With a mass of 2.2 kg, the amplifier can be mounted on lightweight panels or grouped densely in multi-axis cabinets without exceeding typical rail-loading limits.
