Step 6: Step Pulse Type

Most indexers and motion controllers provide motion commands in the “Step and Direction”

format. e Step signal pulses once for each motor step and the direction signal commands

direction. However, a few PLCs use a dierent 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). e 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.
