Pin#Description
1Reduce 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. 
2Current Adjust: Phase Current Adjustment input. A resistor 
connected between this input and the ground input (connector P2,
Pin 3) is used...

Reducing the output current in the MDM60001 can be accomplished by connecting ancurrents.  Shown below are different lead configurations and the procedures to determine
external resistor (1/8 watt or higher) between pins 1 and 2 of connector P2 and ocurrstheir output current.

11124 Lead Motors CONNECTING THE STEP MOTOR
Use the specified series motor current to determine the current adjustment resistor value.
 Four Lead Motors are usually rated with their appropriate series current, as opposed to the
Phase Current which is the rating for 6 and 8 lead motors.  
8 Lead Motors
Series Connection: When configuring the motor windings in series, multiply the per Phase
(or unipolar) current rating by 0.7. Use this result to determine the current adjustment
resistor value.

The MDM60001 has an active LOW open drain output at Connector P1, Pin 7 labeled ONThe Direction and Microstep Resolution Select inputs are synchronized with the positive
F/S OUT.  This output is TRUE (active low) for the duration of the full step.  A full stepgoing edge of the Step Clock input.  When the Step Clock input goes high, the Direction
occurs when either Phase 1&3 or Phase 2&4 cross through zero (ie. full current in oneand Microstep Select inputs are latched and...

1718FAULT PROTECTIONTORQUE/SPEED CURVES
The MDM60001 is internally protected against over temperature, over/under voltage, and
short circuits.
The over temperature set point is between 60C and 70EC.  Care should be taken when
choosing a heatsink so that there is good thermal flow, otherwise hot spots may occur in
the MDM60001 which will reduce the effectiveness of the thermal protection.
The short circuit protection consists of PHASE to PHASE, PHASE to GROUND, and +V
to PHASE.
In the condition where the...
