General Description
The MBC25081TB is a 2.5 amps/phase bipolar microstep driver capable of running four, six and eight lead 
step motors.  The MBC25081TB has an output current range of 0.5 to 2.5 amps/phase and operates off 
12VDC minimum to 24VDC maximum.  The inputs are capable of running from either open collector or 
TTL level logic outputs, or sourcing 24VDC outputs from PLCs.  The MBC25081TB features resolutions 
from 200-1600 steps/revolution, providing smooth rotary operation, built in over...

With JP1 in position 1-2 (sinking) the inputs are considered inactive or Logic “1” if left open, or active or 
Logic “0” if grounded.   With JP1 in position 2-3 (sourcing) the inputs are considered inactive or Logic “0” 
if left open, and active or Logic “1” if pulled to 3.5 - 24VDC.
Setting the Output Current:
The output current on the MBC25081TB is set by the onboard potentiometer.  This potentiometer deter-
mines the per phase peak output current of the driver.  The relationship between the output...

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.
Determine Output Current
The output current for a motor used with a bipolar driver is determined differently from that of a unipolar 
driver.  In the MBC25081TB, a sine/cosine output function is used in rotating the motor.  The output current 
for a given motor is determined by the motors...
