Load Drop Detection – Point Stop (Method 6)
This Load Control press method is similar to Method 3 (Load Drop Detection) except,
once [63: Load Change] has been detected, the press will stop. The press will attempt
to detect this value until it reaches [13: Target Load]. 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 of the peak load (PS) where the decreasing change
in press force equals or exceeds [63: Load Change]. **If JUDGMENT OPERATION is
set to “1” or “3” final load will also be judged.
(See corresponding sections for Interference Check and Part Check explanations.)
[63: Load Change] is a “control” function and is not used for judgment.
If “Interference Check” or “Part Check” are not used, set [15: Interference Check
Load / Part Check Load High] and [17: Part Check Load Low] to [10: CAL
Load] and [23: Interference Check Distance / Part Check Distance] to a
minimum of [21: Distance High Limit].
Review Speed Section explanations and cautions when setting [15: Interference
Check Load / Part Check Load High], [14: Press Speed Start Load], [24: Press
Speed Start Distance] and [20: Approach Distance].
