Introduction IntroductionIntroduction Introduction
Introduction
The MBC10101-75 Microstep Motor Driver has an output current capability of 1.5 Amps minimum to 10.0
Amps maximum (Peak Rating). The MBC10101-75 driver operates from a DC voltage of 8 - 55 Volts. This
driver will out perform all standard 12VDC and 24VDC drivers in the industry. If your system is designed
for a 12VDC or 24VDC specification, this driver will allow your motor to increase its operating output
performance thanks to this outstanding new driver design.
The inputs are optically isolated with a minimum sourcing of 1.0 mA per input (+5VDC minimum to +24VDC
maximum). The clock input is set to receive either positive or negative edge clocks with a maximum
frequency of 100KHz. The MBC10101-75 driver offers direction control, motor current ON/OFF capabili-
ties, and built in short circuit and mis-wire shutdown. The Reduce Current Enabled automatically reduces
motor current to 50% of set value after the last step is made. The driver has built-in features to indicate
power on (Green LED) and Clocks being received, greater than 100 Hz (Yellow LED). The MBC10101-75
has a step resolution of 2000 steps per revolution and the bipolar drive configuration handles 4, 6, and 8
lead motors.

The inputs on the MBC10101-75 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 +5 to +24 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 2. If sinking
current, then all three anodes (+) should be tied together to the +voltage as shown in Figure 1.
The 
optional output on the MBC10101-75 is an opto-decoupled open collector output. When normal op-
eration occurs, this output will conduct current into the emitter. Care must be taken not to pass more than
50mA through this transistor. Please contact Anaheim Automation for functionality of this output.
To enable an input, apply a DC voltage source of +5VDC to +24VDC across the inputs. The Anodes (+)
are pins 1, 3, and 5 on TB1 and the Cathodes (-) are pins 2, 4, and 6 on TB1.

Phase 1 and 3 of the Step Motor is connected between pins 1 and 2 on the TB3.  Phase 2 and 4 of the
Step Motor is connected between pins 3 and 4 on TB3. Refer to Figures 1 & 2 for TYPICAL APPLICA-
TION 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 motor with respect to the direction input, swap the
wires on Phase 1 and  Phase 3.

Power Draw:
The power consumption of this driver from the DC power supply is determined by the DC voltage in. The
power draw is also motor dependent. Motors exceeding 200 watts are not intended for the MBC10101-75
driver. The following formula can be used to determine the maximum power delivered by the driver:
Output Power = (VDC in) x 4.

The output current on the MBC10101-75 is set by an onboard potentiometer. This potentiometer deter-
mines the per phase peak output current of the driver. The relationship between the output current and the
potentiometer value is as follows:

The MBC10101-75 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 MBC10101-75 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 MBC10101-75 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 MBC10101-75.

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 MBC10101-75, 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-
75. 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).

Step Motor Configurations
Step motors can be configured as 4, 6, or 8 leads. Each configuration requires different currents. Refer to
the lead configurations and the procedures to determine their output current.
WARNING! WARNING!WARNING! WARNING!
WARNING! Step motors will run hot even when configured correctly. Damage may occur to the motor if
a higher than specified current is used. Most specified motor currents are maximum values. Care
should be taken to not exceed these ratings.
