7.5.3 STEPPER RESET USING EXTERNAL SWITCH INPUT
From Software revision 619016-002S, it is possible to use an external RESET switch
(
normally closed ) connected between ES1-GND terminals on TS1 to cause a stepper reset.
To enable external reset, the Extended Function parameter [
H!0!
] must be programmed to 06.
Whenever momentary switch is activated (open) the Control will automatically reset the
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 countdown 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 the Schedule to be used.
2. Put the control in PROGRAM mode.
3. Enable Stepper by Programming [
=!Z!
] = 01 or [
=!Z!
] = 02.
4. Program the WELD schedule as required.
5. Select the WELD parameter again.
6. Find [
G!"!
], [
H!"!
], etc. (by pressing the RIGHT Schedule Push-button).
7. Program the desired count in the Data display [
""""
] to [
++++
] (Press ENTER).
8. Reset the Stepper by pushing ENTER, and the two DATA Push-buttons Simultaneously.
9. Put the control back in OPERATE mode.
NOTE
: If necessary, the message [
=!Z!
] [
0!T!J!
] may be shown at the end of the
countdown. Select the next Schedule and clear it by using the Erase Schedule
Shortcut shown on page 3. Program a Weld time of 01 cycles and return to the
operating schedule.
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 parameter.
4. Find [
7!.!
], by pressing the RIGHT Schedule Push-button.
5. Put the Control back in Operate Mode.
The Last Count number will be shown after end of each welding sequence.
7.8 END OF STEPPER
When last step is reached, the Control will flash the message [
=!Z!
] [
0!T!J!
] on displays.
This message can be cleared by pressing any front panel push-button on or by activating E.S.
If [
;!:!
] is programmed to 10 or 17, Process Output Valve, or Valve 3, will be active as long
as message [
=!Z!
] [
0!T!J!
] is flashing on displays.
