The AZBE12A8 is a PWM servo drive designed to drive brushless and brushed DC motors. It has a peak current of 12A, continuous current of 6A, and operates from a 20-80VDC power supply. The drive provides motor commutation and protection from overvoltage, overcurrent, and overheating. It interfaces with digital controllers using analog ±10V commands and supports encoder or tachometer feedback.

- 1. Analog Servo Drive AZBE12A8 Description Power Range The AZBE12A8 PWM servo drive is designed to drive brushless and brushed DC motors at a high switching frequency. To increase system reliability and to reduce cabling costs, the drive is designed for direct integration into your PCB. The AZBE12A8 is fully protected against over-voltage, over-current, over- heating, and short-circuits. A single digital output indicates operating status. The drive interfaces with digital controllers that have analog ±10V output. The AZBE12A8 can utilize quadrature encoder inputs for velocity control. This servo drive requires only a single unregulated isolated DC power supply, and is fully RoHS (Reduction of Hazardous Substances) compliant. See Part Numbering Information on last page of datasheet for additional ordering options.
