Analog Servo Drive 12A8 - Advanced Motion Controls - #1

Text version of the page

Analog Servo Drive 12A8 Description Power Range Peak Current 12 A Continuous Current 6 A Supply Voltage 20 - 80 VDC The 12A8 PWM servo drive is designed to drive brush type DC motors at a high switching frequency. A single red/green LED indicates operating status. The drive is fully protected against over-voltage, 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. See Part Numbering Information on last page of datasheet for additional ordering options. Features .. Four Quadrant Regenerative Operation .. DIP Switch Selectable Modes ..
