Optically Isolated Inputs
The following inputs to the MBC10641 are Optically Isolated.
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 MBC10641 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 MBC10641 is a constant current source, it is not necessary to use a motor that is rated at the
same voltage as the supply voltage. What is important is that the MBC08161 is set to the appropriate
current level based on the motor being used. Higher voltages will cause the current to flow faster through
the motor coils. This in turn means higher step rates can be achieved.
Care should be taken not to exceed
the maximum voltage of the driver.
Anaheim Automation offers a comprehensive line of step motors in 17, 23, 34 and 42 frame
sizes. Contact the factory to verify motor/ drive compatibility.
