							4 Lead Motors
Multiply the specified series motor current by 1.4 to determine the current adjustment potentiom -
eter value.  Four 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 uni-
polar) current rating to determine the current setting potentiometer va\
lue.
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 p\
otentiometer value.
NOTE: After the current has been determined, according to the motor connection above, use 
Table 8 to choose the proper setting for the current setting potentiomete\

							Connecting the Step Motor
Phase 1 and 3 of the step motor is connected between pins 1 and 2 on the motor connector 
(TB3).  Phases 2 and 4 of the step motor are connected between pins 3 and 4 on the motor con-
nector (TB3).  The motor’s case should be grounded to pin 5 on the motor connector (TB3) for 
protection.  Refer to Figures 2 and 3 for TYPICAL APPLICATION HOOK-UP.
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, swap the wires on Phase 1 and Phase 3.  
WARNING: Do not connect or disconnect motor wires while power is applied!
Short-Circuit, Mis-Wire, and Over-Current Conditions
If it is found that there is a condition that causes on over current in the driver phase transistors, 
the Red LED will turn on solid and power will be shut off to the motor.  To reset the drive turn 
power off, check wiring, and turn power back on.
Over-Temperature and Over-Voltage Conditions
If it is found that there is an over temperature on the internal heat sink, or an over voltage on the 
motor bus voltage, the Red LED will blink and power will be shut off to the motor.  To reset the 
drive turn power off, check wiring, and turn power back on.
