MOTOR/DRIVER CONNECTIONS BLD72 DRIVER TERMINAL DESCRIPTION
Figure 3 shows the proper connection of the step motor. The CLOCK (pin 6) PIN FUNCTION DESCRIPTION
and DIRECTION (pin 5) inputs on the driver terminal block are internally
connected to the CLOCK and DIRECTION outputs of the indexer (nothing
should be connected to these inputs).

Phases
1 PHASE 1 MOTOR PHASE 1 (Red motor wire)
2 PHASE 3 MOTOR PHASE 3 (Red/White motor wire)
3 COMMON 1,3 MOTOR PHASE 1,3 COMMON (Black motor wire)
4 FAULT RESET If this input is momentarily pulled low after a fault
condition occurs, then the fault is reset and the driver
can run again.
5 DIRECTION This input is the direction control input. It is internally
connected to the Direction control output of the
Manual Preset Indexer. A logic "1" selects CW(+)
direction. A logic "0" selects CCW (- ) direction.
6 CLOCK IN A negative going pulse on this input causes the
motor to step. The Clock output of the Manual
Preset Indexer is internally connected to this input.
7 0VDC This 0Vdc is internally connected to the 0Vdc on the
Manual Preset Indexer.
8 HS/FS This is the excitation mode select input. A logic "1"
selects HALF-STEP excitation. A logic "0" selects
dual phase FULL-STEP excitation.
9 ON/OFF This input may be used to turn off the motor current
while standing still. This will reduce heating in the
driver and motor. The motor is energized when this
input is a logic "1". The motor is de-energized when
this input is a logic "0".
