Introduction IntroductionIntroduction Introduction
Introduction
The MBC10101 Microstep Motor Driver has an output current capability of 1.5 Amps minimum to 10.0
Amps maximum (Peak Rating). The MBC10101 driver operates from a DC voltage of 20-80 Volts. The
inputs are optically isolated with a minimum sourcing of 1.0 mA per input (+3.5VDC minimum to +8.6VDC
maximum). The clock input is set to receive either positive or negative edge clocks with a maximum
frequency of 100KHz. The MBC10101 driver offers direction control, motor current ON/OFF capabilities,
and built in short circuit and mis-wire shutdown. The Reduce Current Enabled automatically reduces
motor current to 70% of set value after the last step is made (1sec delay). The driver has built-in features
to indicate power on (Green LED) and Clocks being received (Yellow LED). The MBC10101 has a step
resolution of 2000 steps per revolution and the bipolar drive configuration handles 4, 6, and 8 lead motors.

Optically Isolated Input Pin Descriptions
The inputs on the MBC10101 are optically isolated with the anode (+) and cathode (-) both brought out to
the user.  With no current going through the opto-diode the input is considered high. To enable the input
a minimum of 1.0 mA needs to be sourced or sinked through the opto-diode. This is done simply by
placing a voltage of +3.5 to +8.6 VDC across the two inputs of the opto-diode. If sourcing current into the
inputs, then all three cathodes (-) should be tied together and grounded as shown in Figure 3. If sinking
current, then all three anodes (+) should be tied together to the +voltage as shown in Figure 4.
To enable an input, apply a DC voltage source of +5VDC to +8.6VDC across the inputs. The Anodes (+)
are pins 7, 9, and 11 and the Cathodes (-) are pins 8, 10, and 12.

The output current on the MBC10101 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:

Reducing Output Current Reducing Output CurrentReducing Output Current Reducing Output Current
Reducing Output Current
Reducing the output current is accomplished automatically and occurs approximately 1 second after the
last positive going edge of the step clock input. The amount of current per phase in the reduction mode is
approximately 70% of the set current. When the current reduction circuit is activated, the current reduction
resistor is paralleled with the current adjustment potentiometer. This lowers the total resistance value, and
thus lowers the per phase output current.

The MBC10101 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 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.
Since the MBC10101 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 MBC10101 is set to the appropriate
current level based on the motor being used.  Refer to the following chart for setting the current potentiom-
eter based on the current code in the part number of the motor. Examples of motor part numbers are
shown below. Anaheim Automation offers a comprehensive line of step motors in 14, 17, 23, 34 and 42
frame sizes. Contact the factory to verify motor compatibility with the MBC10101.

Determining Output Current Determining Output CurrentDetermining Output Current Determining 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 MBC10101, 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 MBC10101.
This sets the peak output current of the sine/cosine waves. The specified motor current (which is the
unipolar value) is multiplied by a factor of 1.0, 1.4, or 2.0 depending on the motor configuration (series,
half-coil, or parallel).
