INTRODUCTION

The MDM40001 is a High Performance , low cost microstepping driver that incorporates advanced surface mount and ASIC technology. The MDM40001 is compact, easy to interface, and powerful enough to handle the most demanding applications. Anaheim Automation recognizes that cost and size are important criteria in many low and medium power applications. The MDM40001 was designed to meet those needs and offers innovative features.

The MDM40001 will deliver a peak current of 4 Amperes per phase at 40 Volts, providing outstanding motor performance. This advanced technology reduces ripple current while maintaining the 20kHz chopping frequency in the motor, causing less heat in both the motor and drive. In many cases, no special or additional heatsink is required.

With the MDM40001, various step resolutions can be implemented by the on-board dip switches. These divisions range from 400 steps per revolution to 51,200 steps per revolution, and are available in both binary and decimal numbers. The bipolar drive configuration handles 4, 6, and 8 lead motors. Protection devices have been added to this driver for Any-Way-Short-Circuitand Excessive-Temperatureconditions. If an error (short-circuit or excessive-temperature) occurs, a ‘Fault Output’ can be used to inform the machine control of a problem. An ‘At Full Step’ output enables the control to know when the motor is positioned in one of the natural step angles of the motor (typically every 1.8°).
