8 Lead Motors

Series Connection: When conﬁ guring the motor windings in series, use the per phase (or uni-

polar) current rating to determine the current setting potentiometer value.

Parallel Connection: When conﬁ guring the motor windings in parallel, multiply the per phase (or

unipolar) current rating by 2.0 to determine the current setting potentiometer value.

Note: After the current has been determined, according to the motor connections above, use

the potentiometer setting table to choose the proper setting for the current setting potentiometer.

Connecting the Step Motor

The MBC10SI1 is designed to accept one motor. For wiring of the motor refer to the pages con-

taining the connector descriptions and hookups diagrams. The motor is wired into pins 3, 4, 5

and 6 of the terminal block.

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 direc-

tion input, switch the wires on phase 1 and phase 3. With the operation of 2 motors, they will run

in the opposite direction when wired the same.

WARNING: Do not connect or disconnect motor wires while power is applied!

Circuit Protection

This driver is equipped with over current protection.

Note: When drive experiences a fault condition, it will seize to function. Power down, inspect

wiring, motors, etc. and allow for a 30 second pause to resume functioning. If driver is too hot,

additional ventilation and airﬂ ow should be added to prevent temperature to exceed recommended

temperature limit.
