top position sensors/cam switches. When the material is fed, the Gag outputs are activated for the duration of Dwell
time (must be long enough for the punches to go all the way down or the press to pass BDC-bottom dead center,
meaning the press is running in its Single Stroke mode)

Scale is the encoder scaling parameter used to define the number of encoder counts/inch (or mm). It is a numeric
entry. Standard model value is 7355 cnts/inch (289.56 cnts/mm). Heavy Duty model value is 12871 cnts/inch (506.73
cnts/mm).
Direction controls the direction of positive motor rotation. Entering “0” selects CW and a “1” selects CCW.
Debounce is the amount of time each input should stay HI or LOW, in order to be recognized. It is a numeric entry,
with a range of 0 to 999 msec. It is normally set to 1.

Back Length is used to protect the material against bending up by the blade in applications where a cutting device is
the last step of the tool sequence.
