MICROSTEP DRIVERS AND ACCESSORIES 
MDM40001
This is the model number for a Single Axis, 4 Amp Microstep Driver.  The
MDM40001 requires a dc power supply (up to 40 volts). The PSA40V4A is the
recommended power supply that Anaheim Automation supplies.

56PIN DESCRIPTIONS  P2FIGURE 1
Pin#Description
1Fullstep: This OPEN DRAIN output indicates when the driver is
positioned at a full step. This output can be used to count the number of
full steps the motor has moved, regardless of the number of microsteps
in between. This output is active low.
2Fault: This OPEN DRAIN output indicates a fault has occurred (ie.
short circuit or over temperature). This output is active low. 
3Reduction Adjust: Phase Current Reduction Input.  A resistor between
this pin and...

1112STEP MOTOR CONFIGURATIONS4 Lead Motors 
Step motors can be configured as 4, 6, or 8 leads.  Each configuration requires different
currents.  Shown below are different lead configurations and the procedures to
determine their output current.
6 Lead Motors 
When configuring a 6 lead motor in a half-coil configuration (connected from one end
of the coil to the center tap) use the specified per Phase (or unipolar) current rating to
determine the current adjustment resistor value.  This configuration will...

1314CONNECTING THE STEP MOTOR
Phase A of the Step Motor is connected between pins 9 and 10 on connector P2.  Phase
B of the Step Motor is connected between pins 7 and 8 on connector P2.  
Refer to Figure 1 for TYPICAL APPLICATION HOOK-UP
NOTE: The physical direction of the motor with respect to the direction input will
depend on the connection of the motor windings.  To reverse the direction of the motor
with respect
to the direction input, switch the wires on phase A & phase} wires pin 9 & 10.
