Analog Input Trapezoidal Brushless Servo Amplifiers
20-80 VDC Input, 15A cont. (25A pk) @ 20-80 VDC Output
The AB25A100 PWM servo drive is designed to drive brushless and brushed DC motors at a high switching frequency. A single red/green LED indicates operating status. 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.
AxCent™ servo drives can function in the following operating modes:
