7.5.3 STEPPER RESET USING EXTERNAL SWITCH INPUT
Since PROM firmware version 619016-002S, it is possible to use an External Reset switch
(normally closed) connected between TS1-ES1 and TS1-GND to cause STEPPER RESET. To
enable EXTERNAL RESET, EXTENDED FUNCTION
b.E.b.E.
b.E.b.E.
b.E. must be programmed to
0606
0606

Whenever momentary switch is activated (open), control will automatically reset active stepper.
7.6 USING THE STEPPER AS A COUNTER
The stepper counter may be used as a down-counter. It is simply necessary to load a schedule
stepper counter with a value to count down from. The maximum allowable value is 9999. This
function may be used in a single weld schedule, such as 00, 10, 20, 30, or 40, or any welding
sequence starting with those schedules.
1. Select schedule to be used.
2. Put the control in PROGRAM mode.
3. Enable STEPPER by programming

next schedule and clear it by using the clear data shortcut (see Section 5.4.5). Program a
WELD time of 01 cycles and return to the OPERATE mode.
7.7 DISPLAYING THE STEPPER COUNT DURING OPERATION
The stepper count may be displayed during operation if necessary. Since this is not a principal
WELD function, the access to the display requires the following:
1. Select the schedule to be used.
2. Put the control in PROGRAM mode.
3. Select the WELD/HEAT parameter.
4. Find
