Product Description:

The PQM0PA37000 servo amplifier is produced by Sanyo Denki and supplied under the PQ Type M Servo Amplifiers series. Designed as the power interface between a motion controller and three-phase servomotors, it converts incoming mains power into regulated drive voltage and monitors feedback to maintain commanded torque and velocity. In automated machine tools, packaging lines, and pick-and-place modules, the unit forms the core of the axis drive by coordinating motor dynamics while occupying less cabinet space than separate power and control modules.

For its signal section, the amplifier requires a single-phase 200 VAC control circuit input, which isolates low-power logic from the motor bus. This channel draws up to 200 VA, allowing the auxiliary transformer to be sized for the required load. A startup surge of 40 A occurs on the control line, so breakers or soft-start devices must tolerate this brief inrush without nuisance tripping. The power stage accepts a three-phase 200 VAC main supply and can demand as much as 64 kVA during rated acceleration, establishing the feeder and contactor capacity required for full-load performance. These electrical characteristics make the amplifier compatible with typical Japanese and North American 200-volt plant power systems.

Once energized, the amplifier can deliver a continuous output of 37 kW, enabling medium-sized servomotors to execute rapid cycles without voltage sag. Excess kinetic energy is dissipated through an internal resistor bank with a minimum impedance of 1.3 Ω, protecting the DC link during deceleration. The housing is fabricated from SPCC steel with a black chromate finish and weighs 22.0 kg, so the mounting rails and supporting panel must accommodate its static load. Reliable operation is maintained at ambient temperatures up to 131 °F, at relative humidity levels up to 90%, and at elevations up to 1,000 m. During storage, the surrounding temperature must not exceed 149 °F.
