Step 6: Step Pulse Type
Most indexers and motion controllers provide motion commands in the “Step and Direction”
format. The Step signal pulses once for each motor step and the direction signal commands
direction. However, a few PLCs use a different type of command signal: one signal pulses once
for each desired step in the clockwise direction (called STEP CW), while a second signal pulses
for counterclockwise motion (STEP CCW).
The STR drives can accept this
type of signal if you remove the
drive cover and move jumper
S3 from the “1-2” position to
the “1-3” position. In STEP CW/
STEP CCW mode, the CW signal
should be connected to the STEP
input and the CCW signal to the
DIR input.
