Connecting the Step Motor
Phase 1 and 3 of the Step Motor is connected between pins 1 and 2 on connector TB2.  Phase 2 and 4 of
the Step Motor is connected between pins 3 and 4 on connector TB2.  The motors case can be grounded
to pin 5 on connector TB2. Refer to the figures above for typical application hookup drawings. The physi-
cal direction of the motor with respect to the direction input will depend on the...

This unit is equipped with a fan on the reverse side. When mounted, there should be at least  1 inch of
clearance for air flow to enter the unit. Also to help the chassis from overheating, it is recommended
that the unit be mounted to a larger aluminum plate or other heat conducting surface.
Microstep Selection (SW1 Settings)
Switches 1, and 2 of the DIP switch select the resolution of the microsteps per fullstep. The following table
shows the standard resolution values along with the associated...

Motor Selection
The MLP07081 is a Bipolar Microstep Driver that is compatible with both Bipolar and Unipolar Motor
Configurations, (i.e. 8 and 4 lead motors, and 6 lead center tapped motors). Since the MLP07081 is a
constant current source, it is not necessary to use a motor that is rated at 160V which is the motor supply
voltage. What is important is that the MLP07081 is set to the appropriate current level based on the motor
being used. The higher voltage of this drive will cause the current to flow...

4 Lead Motors
Multiply the specified series motor current by 1.4 to determine the current adjustment potentiometer
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.

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), multiply the specified per Phase (or unipolar) current rating by 1.4 to determine the current
setting potentiometer value. This configuration will provide more torque at higher speeds when compared
to the series configuration.
When configuring the motor in a series configuration (connected from end to end with the
center tap floating) use the specified per Phase (or...
