If you’re looking for high performance in a small driver, the MBC12101 is your answer.  This powerful microstepping 
driver provides excellent torque in a compact and low profile encloser .  The MBC12101 is also very easy to use.  It 
features rugged terminal blocks, a rotary pot for current settings, and a visible silkscreen for easy 
installation.
The MBC12101 features optically isolated inputs that are 3.5 - 8.6VDC compatible.   The clock input can be set to 
receive either sinking or sourcing clock signals at frequencies up to 100KHz.   The driver also features direction 
control, motor on/off capabilities, and a built in short circuit and miswire shutdown protection.
The MBC12101 is a bipolar type driver designed for use with 4, 6, or 8 lead stepper motors, making it compatible 
for series and parallel installations.  The driver has a 2000 steps per revolution or 0.18° per step resolution,with 
respect to a 1.8° stepper motor.  It also has a motor current reduction feature that will help keep stepper motors 
cool at standstill, and LEDs that indicate power and pulses being received.

Optically Isolated Input Pin Descriptions
The inputs of the MBC12101 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 1.0mA 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.  If  sinking 
current, then all three anodes (+) should be tied together to the +voltage as shown in theTYPICAL APPLICATION HOOK-UP.
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.
Pin #Description
1 0VDC: Return path for driver voltage
2 20-80 VDC:  Input voltage for the driver (+20-80VDC)
3 A: Phase 1 of the Step Motor
4 A\: Phase 3 of the Step Motor
5 B: Phase 2 of the Step Motor
6 B\: Phase 4 of the Step Motor
7 ON/OFF+:
  On/Off Anode (+) - This isolated input is used to enable and disable the output section of the driver. When HIGH 
(open) the outputs are enabled. However, this input does not inhibit the step clock.
8 ON/OFF-:  On/Off Cathode (-)
9 Dir+: 
Direction Anode (+) - This isolated input is used to change the direction of the motor. Physical direction also depends 
on the connection of the motor windings.
10 DIR-: Direction Cathode (-)
11 CLOCK+: 
Step Clock Input Anode (+) - A positive going edge on this isolated input advances the motor one increment. The 
size of the increment is dependent on the Microstep Select Inputs of Switch 1.
12 CLOCK-: Step Clock Input Cathode (-)
12 Pin Terminal Block Description Connecting the Step Motor
Phase 1 (A) and 3 (A\) of the Step Motor is connected between pins 3 and  4 on the terminal block connector.  Phase 2 (B)
and 4 (B\) of the Step Motor is connected between pins 5 and 6 on the terminal block connector . 
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.
WARNING: Do not connect or disconnect motor wires while power is applied! This driver does not protect itself if 
the motor is disconnected while powered.

Reducing Output Current
Reducing  the  output  current  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 50% of the set current. Reducing the output current is 
accomplished when no current flows through the opto-diode at the CLOCK (+) and CLOCK (-) pins after the last step has 
occurred. The clock LED should be off at this time. The output current on the MBC12101 is set by an onboard potentiometer. This potentiometer determines the per phase peak 
output current of the driver. 
Peak CurrentPotentiometer Setting Peak CurrentPotentiometer Setting
1.5A 0%7.0A 60%
2.3A 10%7.9A70%
3.0A 20%8.7A80%
4.0A 30%9.6A90%
5.0A 40% 10A100%
6.0A 50% ----
Setting the Output Current:
The specified motor current of 5.0A for the 34Y314S-LW8-MS (which is the bipolar value) is multiplied by a factor of 
1.4 to determine the current adjustment potentiometer value of 7.0Amps o\
r 60%. 
WARNING: Do not set the current setting above the step motors rated current. When using a  higher current setting 
into a motor, the motor will overheat and burn up. Should this occur, the driver will also be damaged.
