the movement times are not increased. The time increase may be left deactivated or
arbitrarily associated with one of the two available stepper laws.
STEPPER THICK.
This parameter may be modified only if the sensors that check for the position of the
electrodes have been correctly installed in the spot welder. If affirmative, the parameter may
be changed and consequently it will be possible to define a law that corrects the thickness
reduction of the electrodes caused by wear and tear. The correction permits to maintain the
exact measurement of the initial thickness of the sheets to be welded. Otherwise if the
electrodes are very worn out and the operator does not wish to resort to a stepper law, the
zero procedure may be carried out more often than the rate at which the change in size of the
electrodes is corrected.
The parameter may be left deactivated or arbitrarily associated with one of the two available
stepper laws.
N.TOTAL STEPS
This parameter indicates by how many segments the current stepper curve is to be made up
of. In order to deactivate the stepper module function, STEPPER WELD. and STEPPER
TIME and STEPPER THICK must all be OFF.
SPOTS 1
This parameter indicates the number of spots which the associated segment is composed of.
When STEPPER 1-L1 = 0 and SPOTS 1
≠
0, the value set in parameter SPOTS 1 equals the
max number of weld spots.
INCREMENT 1-L1
This increment indicates the percentage increase relevant to the first segment of stepper law 1.
INCREMENT 1-L2
This increment indicates the percentage increase relevant to the first segment of stepper law 2.
SPOTS 2
This parameter indicates the number of spots which the associated segment is composed of.
INCREMENT 2-L1
This increment indicates the percentage increase relevant to the second segment of stepper
law 1.
INCREMENT 2-L2
This increment indicates the percentage increase relevant to the second segment of stepper
law 2.
SPOTS 3
This parameter indicates the number of spots which the associated segment is composed of.
INCREMENT 3-L1
This increment indicates the percentage increase relevant to the third segment of stepper law
1.
