Time Controlled Press (Method 3)

This Load Control press method allows a pressing operation to be performed based off
of a given time [42: 2

ND

Time].

Upon start of cycle, the press will operate until it achieves [13: Standard Load]. During
the press cycle, after achieving [18: Crossover Load], the press rate will be current
controlled to achieve [13: Standard Load] in proportion to the time specified in
[42: 2

ND

Time] (Example: if [42: 2

ND

Time] is set to 10 seconds, it will take 10 seconds

to go from [18: Crossover Load] to [13: Standard Load])

. During the press cycle,

checks are performed for “1

ST

Judgment Zone”, 1

ST

Rate, 2

ND

Rate, Load, Distance

and 1

ST

Time. If any of these values are compromised, the press will stop and return as

programmed.
(See corresponding sections for Time, Rate, 1

ST

Zone and Speed explanations.)

This press can be done with an ‘F’ type tool but make sure not to overload.



ƒ

In this special setup, [42: 2

ND

Time] 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].
