♦ Load Rise Detection (Method 3)
This Load Control press method allows judgment of a distance (DS) at a given press
rate [19: Load Rate Change].
Upon start of cycle, the press will operate until it achieves [14: Target Load]. During
the press cycle, as soon as [39: Detection Start Distance] is reached, a rate
calculation will begin based upon the load seen at a distance of .1mm before the
[39: Detection Start Distance] point and will continue to be calculated every .1mm
until [19: Load Rate Change] is exceeded. During the press cycle, checks are
performed for “Interference Check” / “Part Check”, Load and Distance. If any of these
values are compromised, the press will stop and return as programmed.
Final
Judgment is based on the distance where the rate exceeds [19: Load Rate Change]
after [39: Detection Start Distance] has been reached
.
(See corresponding sections for Interference Check and Part Check explanations.)
ƒ [19: Load Rate Change] is a “control” function and is not used for judgment.
ƒ
Load Rate Change = (Load @ (DS+.1mm) - Load @ (DS)) x 10
* To determine Load Rate Change, view CSV data file for a good part.
