Item Pin # Clock 1 & 2 Direction 3 & 4 On/Off 5 & 6 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. December 2004 Microstep Selection (SW1 Settings) Switches 2, 3 and 4, of the DIP switch select the number of microsteps per step. Table 7 shows the standard resolution values along with the associated positions for the select switches. The standard waveforms are sinusoidal.

Setting the Output Current The output current on the MBC10641 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 potentiometer value is as follows: Peak Current Potentiometer Setting Peak Current Potentiometer Setting 1.5A 0% 7.0A 60% 2.3A 10% 7.9A 70% 3.1A 20% 8.7A 80% 4.0A 30% 9.6A 90% 5.0A 40% 10A 100% 6.0A 50% -- Table 7: Potentiometer values with respect to the output current Refer to Table 5 for specific motor current settings.
