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.
