4 Lead Motors
Multiply the specified
series
motor current by 1.4 to determine the current adjustment potentiometer value.
4 lead motors are usually rated with their appropriate series current, as opposed to the
Phase Current
,
which is the rating for 6 and 8 lead motors.
8 Lead Motors
Series Connection:
When configuring the motor windings in series, use the per phase (or unipolar) cur
-
rent rating to determine the current setting potentiometer value.
Parallel Connection:
When configuring 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 poten-
tiometer setting table to choose the proper setting for the current setting potentiometer.
Connecting the Step Motor
The MBC25PG1(L) is designed to accept either one or two motors. For wiring of the motor refer to the
pages containg the connector descriptions and hookup diagrams.
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, 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 short circuit, over temperature and cross 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
airflow should be added to prevent temperature to exceed recommended temperature.
