The MDM60001 is a High Performance, low cost microstepping driver that incorporates advanced su rface mount and ASIC technology. The MDM60001 is compact, easy t o interfac and powerful enough to handle the most demanding applications. Anahei m A n recognizes that cost and size are important criteria in many low and medium power appl ications. The MDM60001 was designed to meet those needs and offer s innovative features.

The size of the increment is dependent on the Microstep Select Inputs of Switch 1. 2 Direction: This isolated input is used to change the direction of the motor. Physical direction also depends on the 65VDC Power Supply connection of the motor windings. 65VDC Power Supply 3 This input is used to supply current to the Is

: 1 Phase Current Reduction Input. A resistor between this pin and pin 2 (Connector P2, Current Adjust) will proportionately reduced the current in both windings (1 second after the last positive going edge of the step clock input). The amount of current reduction will depend on the value of the resistor used. 2 Phase Current Adjustment input. A resistor connected between this input and the ground input (connector P2, Pin 3) is used to adjust the maximum Phase Current in the motor. A 3 Suppl
