7.4.2 STEPPER OPERATION FOR STEPPER MODE
[
=!Z!
]=
"$
In this mode, the maximum number of steps is 50, which is possible only if a single schedule
is used per step. If more chained schedules are required in a welding sequence, the number
of steps is determined by the number of chained schedules used in each step.
The algorithm is almost identical to that one used for stepper mode 01, shown in Figure 7.6,
except that only
one stepper counter is used and when the Last Step is incremented, the
Control will check if that number is greater than the maximum number of schedules, 49 in
this case, and then show End of Stepper message, if necessary. Also, stepper counter will be
decremented only if FS3 (or both FS7-FS11 in anti tiedown mode) is used for initiation.
The following table demonstrates this mode with 5 chained schedules per step or welding
sequence. Weld count
must be programmed in the first schedule of the chained sequence.
Following the last step, the next schedule should be empty, in this example schedule 17. If
weld count in that schedule is 0000 that will indicate End of Stepper, [
=!Z!
] - [
0!T!J!
] .

buttons at the same time, the Last Step will be [
