The MBC100 is a low-cost bipolar chopper driver designed to drive four-phase step motors rated up to 1A. The
MBC100 is compact and self-contained, requiring only an 8VDC - 40VDC power source and clock input to operate. The
maximum motor current can be adjusted from 200mA to 1A, by adjusting a potentiometer on the unit; no external
resistors are required to set the current level. The inputs to the driver are of the sinking type for easy interfacing with
other equipment. An ON/OFF input is provided, which allows the motor to be turned off without powering down the
driver. The Halfstep/Fullstep input selects half-step or full-step operation. A direction input is also provided. When the
motor has been at standstill for 2 seconds, the driver will enter a reduced current mode. The user can select the
standstill reduced current to be 100% (no reduction), 66%, or 33% of the selected current level. A clock indicator is lit
while clock inputs are being received by the driver, and turns off shortly (~1 sec.) after the clock stops. The MBC100 is
a small, rugged package that is easy to mount horizontally or vertically by its integrated mounting bracket. The
CURRENT SETTING potentiometer on the top of the driver should be set to the desired maximum motor current level
before operating the driver. The input and output connections for the MBC100 are described in the following tables:
CONNECTOR DB2 ( MOTOR )
The MBC100 has a green POWER indicator that is lit when the unit has a supply voltage in the proper range. The
CLOCK indicator is lit whenever the unit is receiving clock signals. This indicator will turn off shortly (~1 sec.) after
clocking stops.
