ACD4000 Motor Drive

The ACD4000 motor drive from Performance Controls, Inc. (PCI) is an AC servo amplifier designed for operating in extended temperature environments. It utilizes a high performance Digital Signal Processor (DSP), high efficiency MOSFET’s and proprietary control techniques to provide smooth, reliable motor control and programming flexibility. Parameters are available to optimize motor performance, set acceleration/deceleration, set forward/reverse speed limits, and provide other functions. The ACD4000 motor drive can be customized with expanded voltage or current ranges, alternative form factors, OEM labeling, and other features.

  • For Brushless Permanent Magnet and AC Induction Motors

  • 300 VDC

  • 15 A Continuous, 22 A Peak

  • 4 Quadrant Operation

  • Extended Temperature Operation



The ACD4000 Digital Servo Amplifier can be used in these and other applications:

  • Radar, antenna positioning
  • Power generation applications
  • Remote applications with extended temperature environments

High Temperature Operation

Base plate operating range of -40 to 175 °F (-40 to 80 °C).

Digital Tuning

Optimizes performance, enables cloning, eliminates pot drift, and reduces inventory through the use of the same drive for multiple applications.

Advanced Commutation

Space Vector Commutation for better bus voltage utilization for improved torque/speed curves compared with standard sinusoidal or trapezoidal commutation.

Flux Vector Current Control

Provides improved current utilization.

Health Monitor (Data Logger)

Logs faults, warnings, alarms, and peak values to non-volatile memory for system maintenance and repair.

Sensorless Control

Option to eliminate the resolver and resolver cable without sacrificing the advantages of the advanced commutation

Electrical Isolation

Eliminates the need for external isolation circuits.

“Get Me Home” Over-Temperature Warning Mode

Provides warning and linear reduction of current limit to allow continued operation at reduced capacity for a controlled shutdown.
