The AZB20A8 is a PWM servo drive designed to drive brushless and brushed DC motors at high switching frequencies. It has a peak current of 20A, continuous current of 12A, and operates on a 10-80VDC supply voltage. The drive provides hardware protection against over/under voltage, over-current, over-heating and short circuits. It interfaces with digital controllers using a +/- 10V analog command input.

- 1. Analog Servo Drive AZB20A8 Description Power Range The AZB20A8 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 AZB20A8 is fully protected against over-voltage, under-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. 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.

- 2. Analog Servo Drive AZB20A8 BLOCK DIAGRAM Information on Approvals and Compliances US and Canadian safety compliance with UL 508c, the industrial standard for power conversion electronics. UL registered under file number E140173. Note that machine components compliant with UL are considered UL registered as opposed to UL listed as would be the case for commercial products. Compliant with European CE for both the Class A EMC Directive 2004/108/EC on Electromagnetic Compatibility (specifically EN 61000-6-4:2007 and EN 61000-6-2:2005) and LVD requirements of directive 2006/95/EC (specifically EN 60204-1:2006), a low voltage directive to protect users from electrical shock. RoHS (Reduction of Hazardous Substances) is intended to prevent hazardous substances such as lead from being manufactured in electrical and electronic equipment.

Maximum duration of peak current is ~2 seconds. Peak RMS value must not exceed continuous current rating of the drive. 2. Lower inductance is acceptable for bus voltages well below maximum. Use external inductance to meet requirements. 3. Additional cooling and/or heatsink may be required to achieve rated performance.
