Chapter 6: System Operation
♦ Time Controlled Press (Method 3)
This Load Control press method allows a pressing operation to be performed based off
of a given time [42: Press Time].
Upon start of cycle, the press will operate until it achieves [13: Target Load]. During
the press cycle, after achieving [18: Time Start Load], the press speed will be
adjusted to achieve [13: Target Load] in proportion to the time specified in
[42: Press Time] (Example: if [42: Press Time] is set to 10 seconds, it will take 10
seconds to go from [18: Time Start Load] to [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.
(See corresponding sections for Interference Check and Part Check explanations.)
This press can be done with an ‘F’ type tool but make sure not to overload.
ƒ In this special setup, [42: Press Time] is a “control” function and is not used for
judgment.
ƒ 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].
ƒ 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].
ƒ To use this method in a Step Press Operation, refer to page 6-3.
