Product Description:
The PQM0PA27000 servo amplifier is produced by Sanyo Denki and belongs to the PQ Type M Servo Amplifiers series. Designed for factory automation, it converts incoming mains power and control commands into regulated drive waveforms that govern motor speed, position, and torque. By closing the loop between a motion controller and an AC servo motor, the unit supports coordinated multi-axis movements needed in packaging, pick-and-place, and cutting systems. Its power stage supplies the controlled electrical output required to operate compatible servo motors, while the control section processes motion commands and feedback signals.
At the power stage, the amplifier accepts a three-phase input of 200 VAC, and its input apparent power can reach 46 kVA during operation. Under these conditions, it delivers a continuous motor output of 27 kW with an input frequency of 50/60 Hz. The main circuit tolerates supply variations of +10%/-15%, helping the amplifier continue operating during brief voltage fluctuations. The control electronics use an isolated, single-phase 200 VAC supply rated at 200 VA. This control supply permits a frequency variation of ±3 Hz without disrupting gate timing. The separate three-phase power and single-phase control feeds isolate high-power switching from low-level signal processing while remaining compatible with common industrial power systems.
The drive can operate at altitudes up to 1000 m and in ambient humidity levels reaching 90% RH. These operating limits should be observed when the amplifier is installed in an industrial control cabinet. Excess regenerative energy is routed to an external braking network that must provide a resistance of at least 2.5 Ω to prevent excessive current in the transistor stack. This external network dissipates energy returned by the motor during rapid deceleration or braking. The amplifier has a mass of 16 kg, allowing its mounting surface and fasteners to be selected for the applied load. Adequate cabinet space should also be provided for the power wiring, control connections, and external braking components associated with the drive.
