When the batch counter reaches the programmed batch count, the
Batch
Count Reached
output is activated and the batch counter is cleared. The
output will be de-activated automatically on the next
Cycle Count.
The
batch counter may also be cleared by the
Reset Batch Counter
input
function 75. The range is 0 to 2,147,483,648.
Cycle Count
This parameter is used in conjunction with the
Cycle Count Reached
output function 42.
See
Batch Count
.
The cycle counter is incremented each time a cycle is completed unless
the
Cycle Counter Hold
input function 76 is active. When the cycle
counter reaches the programmed cycle count, the batch counter is
incremented and the cycle counter is cleared. The
Cycle Count Reached
output is cleared when the next cycle is completed. The cycle counter
and
Cycle Count Reached
output may also be cleared by the
Reset Cycle
Counter
input function 74. The range is 0 to 2,147,483,648. See the
FF
and KC4

Working Segment Width
This is also called the
Working Segment
. This parameter is the distance
that the Follower moves at the
Working Ratio
. The position of this
segment is centered around the
Cycle Point
which is determined by the
Working Offset
. See Figure 27.

A good starting point is to set the
Working Segment
at 30 percent of the
shorter of the Master length or Follower length.
It should be kept between 15 percent and 65 percent of the shorter of the
Master or Follower length.
For example:
The Master length is 10 inches and the Follower length is 5 inches. The
Follower axis is in contact with the material for 0.5 inches. This may be
too short of a
Working Segment
for many systems to perform a good
operation on the material. A better choice to start at would be 30 percent
of the Follower length, which is 1.5 inches, for a
Working Segment
.
