Hook Up Drawings
Optically Isolated Inputs
The following inputs to the MBC08161 are Optically Isolated. Optional: Non-Isolated +5VDC Output can power the MBC08161 Inputs (but isolation is eliminated).
Figure 3: Hook Up for Current Sinking Inputs
To enable an input, apply a DC voltage source of +5VDC to +24VDC across the inputs. The Anodes (+)
are pins 1,3,and 5 and the Cathodes (-) are pins 2, 4, and 6.

Motor Selection
The MBC08161 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.
Since the MBC08161 is a constant current...

Microstep Selection (SW1 Settings)
Switches 2, 3 and 4, of the DIP switch select the number of microsteps per step. Table 6 shows the
standard resolution values along with the associated positions for the select switches. The standard wave-
forms are sinusoidal.
Setting the Output Current
The output current on the MBC08161 is set by an onboard potentiometer. This potentiometer determines
the per phase peak output current of the driver. The relationship between the output current and the...

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...

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 configuring...

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 Figures 2, 3 & 4 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...
