♦ Load Rise Detection (Method 2 – Type 2)
This Load Control press method allows judgment of a distance (DS) at a given load
[18: Crossover Load] and press rate [33: Rate 2 High].
Type 2 Control is active if [22: Standard Distance] is set to 0.
Upon start of cycle, the press will operate until it achieves [13: Standard Load]. During
the press cycle, as soon as [18: Crossover Load] is achieved, a rate calculation will
begin based upon the load seen at a distance of .1mm before the [18: Crossover
Load] distance and will continue to be calculated every .1mm until [33: Rate 2 High] is
exceeded. During the press cycle, checks are performed for “1
ST Judgment Zone”, 1 ST
Rate, Load, Distance, 1 ST Time and 2 ND Time. 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 [33: Rate 2 High] after [18: Crossover Load] has been
achieved.
(See corresponding sections for Time, Rate, 1
ST Zone and Speed explanations.)
ƒ [33: Rate 2 High] is a “control” function and is not used for judgment.
ƒ If “1 ST Judgment Zone” is not used, set [15: 1 ST Load] to [10: CAL Load] and
[23: 1 ST Distance] to a minimum of [21: High Distance].
ƒ Review Speed Section explanations and cautions when setting [15: 1 ST Load], [14:
Speed Change Load], [24: Crossover Distance] and [20: Freerun Distance].
ƒ If 1 ST Rate is not used, set judgment windows wide open; low value of 0 and
maximum high value. Also, if 1 ST H/L Check is not being used, set [17: Threshold
Load] to [10: CAL Load].
