Motor Selection
The MBC061281 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).
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 5, 6, 7 and 8, of the DIP switch select the number of microsteps per step. The following table
shows the standard resolution values along with the associated positions for the dip switches. The stan-
dard waveforms are sinusoidal.
Setting the Output Current
The output current on the MBC061281 is set by Switches 1, 2 and 3. The position determines the per
phase peak output current of the driver. The relationship between the output current...

Determining Output Current
The output current for the motor used when microstepping is determined differently from that of a full/half
step unipolar driver. In the MBC061281, a sine/cosine output function is used in rotating the motor. The
output current for a given motor is determined by the motors current rating and the wiring configuration of
the motor. There is a current adjustment potentiometer used to set the output current of the MBC061281.
This sets the peak output current of...

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 (A) and 3 (A\) of the Step Motor is connected between pins 3 and 4 on the motor connector (TB3).
Phase 2 (B) and 4 (B\) of the Step Motor is connected between pins 5 and 6 on the motor connector
(TB3).Refer to Figures 1 and  2 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...
