Target current =
(%I programmed in Function #20 + Stepper boost) x C-Factor
= (50 + 2) x 170 = 8,840 A.
To determine the High Current Limit:
High Current Limit = (Target x %High Limit/100)
= 8,840 + (8,840 x 10/100)
= 8,840 + (884) = 9,724 A.
To determine the Low Current Limit:
Low Current Limit = Target – (Target x %Low Limit/100)
= 8,840 – (8,840 x 20/100)
= 8,840 – (1,768) = 7,072 A.
ACC Firing Mode
In this firing mode, the target value is established by the following
calculation:
Target current = A. in Function #30 + Stepper boost
An example of how these calculations are used is shown below.
• Function #30 is WELD 08 CY 11000 A. SEC
• Stepper Boost is 700 A. SEC
• High Current Limit = 10%
• Low Current Limit = 20%
To determine the Target Current:
Target current = A. in Function #30 + stepper boost
= 11,000 + 700 = 11,700 A.
To determine the High Current limit:
High Current Limit = (Target x %High limit/100)
= 11,700 + (11,700 x 10/100)
= 11,700 + (1170) = 12,870 A.
To determine the Low Current Limit:
Low Current Limit = Target – (Target x %Low limit/100)
= 11,700 – (11,700 x 20/100)
= 11,700 – 2,340 = 9,360 A.
