Motor Selection
The MLU10641 is a Bipolar Microstep Driver that is compatible with both Bipolar and Unipolar Motor Con-
figurations, (i.e. 8 and 4 lead motors, and 6 lead center tapped motors).
Step motors with low current ratings and high inductance will perform better at low speeds, providing
higher low-end torque. Motors with high current ratings and low inductance will perform better at higher
speeds, providing more high-end torque. Higher voltages will cause the current to flow...

Microstep Selection (SW1 Settings)
Switches 2, 3 and 4, of the DIP switch select the microstep resolution of the driver. Table 6 shows the
standard resolution values along with the associated positions for the select switches. The standard wave-
forms are sinusoidal. The steps/rev are based on a 200 step/rev motor.
Setting the Output Current
The output current on the MLU10641 is set by an onboard potentiometer. This potentiometer determines
the per phase peak output current of the...

When configuring the motor in a series configuration (connected from end to end with the center tap
floating) use the specified per Phase (or unipolar) current rating to determine the current setting potenti-
ometer value.
Reducing Output Current
Reducing the output current is accomplished by setting switch 1 of the DIP switch to the ON position and
occurs approximately after the last positive going edge of the step clock input. The amount of current per
phase in the reduction mode...

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.
8 Lead Motors
Series Connection: When configuring the motor windings in series, use the per Phase (or unipolar)
current rating to determine the current setting potentiometer value.
Parallel Connection: When...

Connecting the Step Motor
Phase 1 and 3 of the step motor is connected between pins 1 and 2 on the motor connector (TB3).  Phase
2 and 4 of the step motor is connected between pins 3 and 4 on the motor connector (TB3).  The motors
case should be grounded to pin 5 on the motor connector (TB3) for protection. Refer to Figures 2 and 3 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...
