The MDM60001 was designed to meet those needs and offers innovative features. The MDM60001 will deliver a peak current of 6 Amperes per phase at 75 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. -
Page 3: Ordering Information
This is the model number for a Single Axis, 4 Amp Microstep Driver. The MDM40001 requires a dc power supply (up to 48 volts). MDM60001 This is the model number for a Single Axis, 6 Amp Microstep Driver. MDM60001 requires a 65Vdc power supply (PSA65V5A-2) that Anaheim Automation provides, purchased separately. - Page 4 PIN DESCRIPTIONS P2 Pin# Description Reduce Current: 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.

(half-coil, series, or parallel). 15 mA Max SETTING OUTPUT CURRENT The output current on the MDM60001 is set by an external ±1%, 1/8 watt (or higher) resistor between pins 2 and 3 of connector P2. This resistor determines the per Phase RMS UNIT output current of the driver. -
Page 6: Reducing Output Current
Since the MDM60001 is a constant current source, it is not necessary to use a motor that is rated at the same voltage as the supply voltage. What is important is that the MDM60001 is set to the appropriate current level based on the motor being used. -
Page 7: Connecting The Step Motor
WARNING: Do not connect or disconnect motor wires while power is applied! CONNECTING POWER Pins 3 and 4 on connector P2 are used to connect the DC Power Supply to the MDM60001. Wire size used to connect the power source to the driver should be at least 16 gauge. -

Page 9: Fullstep Output Signal
FULLSTEP OUTPUT SIGNAL The MDM60001 has an active LOW open drain output at Connector P1, Pin 7 labeled ON F/S OUT. This output is TRUE (active low) for the duration of the full step. A full step occurs when either Phase 1&3 or Phase 2&4 cross through zero (ie. full current in one winding and 0 current in the other winding). -
Page 10: Fault Protection
In the condition where the DC voltage of the driver exceeds approximately 82 volts, the driver will execute a fault. If any fault is detected by the MDM60001, the outputs will be disabled and can not be re- enabled without resetting or powering down the driver. At the same time the open collector FAULT output is turned on. - Page 11 Notes: TORQUE/SPEED CURVES...
