Current Range
Set SW3-#7 and SW3-#8 to select a range for motor current
settings. In
Step 6
of the
Quick Test
you installed a resistor
that determines motor current. Be sure that SW3-#7 and
SW3-#8 are set to the proper current range for the resistor
you installed.

For every step pulse it receives on its step input, the drive will
commutate the motor to increment rotor position. To send a
step pulse to the drive, apply a positive voltage to
STEP+
with
respect to
STEP–
. The drive registers the pulse on the rising
edge.
The step input is optically isolated. Driving the step input
differentially will provide the best noise immunity. Your input
driver must provide a minimum of 6.5 mA—
approximately 3.5
