Advanced Motion Controls Presents AB25A100 PWM Servo Drive with Offset Adjusting Potentiometer

Press Release Summary:

The AB25A100 PWM Servo Drive is designed for driving brushless and brushed DC motors at high switching frequency. The drive comes with built-in hardware protection such as overvoltage, under-voltage, over-current, over-heating and short-circuits. The unit is offered with DIP switches and potentiometers for loop turning, current limit adjustments and drive configuration. It accepts 20-80 VDC input and delivers 15 A and 25 A continuous and peak output current respectively. The AB25A100 provides velocity feedback via incremental encoder, hall sensors, or tachometer.

Original Press Release:

New AB25A100 Panel Mount Servo Drive Provides Centralized Control & Offers High Bandwidth & Quick Response Times

The AB25A100 PWM servo drive from Advanced Motion Controls is designed to drive brushless and brushed DC motors at a high switching frequency. 

The drive is fully protected against overvoltage, under-voltage, over-current, over-heating and short-circuits across motor, ground and power leads. Furthermore, the drive can interface with digital controllers or be used stand-alone, and requires only a single unregulated DC power supply. Loop gain, current limit, input gain and offset can be adjusted using 14-turn potentiometers. The offset adjusting potentiometer can also be used as an on-board input signal for testing purposes. This drive can use quadrature encoder inputs for velocity control. Features include:

  • 20-80 VDC Input, 15 A Cont. (25 Peak) Output
  • Built-in hardware protection - Over Current, Over Voltage, Under Voltage, Over Temperature, Short Circuit
  • DIP Switches and Potentiometers for loop tuning, current limit adjustments and drive configuration
  • Standard models support both brushless and brushed motor types
  • Velocity feedback via incremental encoder, Hall Sensors, or tachometer
  • Optical isolation between high and low power signals standard on certain models
  • Current, Velocity, and Fault Monitor analog output signals
  • Status LEDs for power and drive status
  • Four quadrant regenerative operation
