Connecting the Step Motor
Phase 1 and 3 of the Step Motor is connected between pins 1 and 2 on the motor connector
(TB2). Phase 2 and 4 of the Step Motor is connected between pins 3 and 4 on the motor con-
nector (TB2). The motors case can be grounded to pin 5 on the motor connector (TB2). Refer
to figures 2, 3, & 4 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, switch 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 Current Conditions
If it is found that there is 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.
