Basic Characteristics RAPID

Routines
The following predefined routines are installed with the application. They are all used
by the SpotL instruction.
These routines have a default functionality but can easily be changed.
User defined supervision routines for SpotL:
The following routines are called by the SpotL sequence.
PROC sw_preweld_sup ()
The routine is executed before each start of the weld process.
spotweld preweld supervision
If an error text is assigned to the text string errtext, then the system is automatically
stopped with the error text on the display and with a possibility to restart the supervision
routine and continue the program execution.
Default functionality:
If the simulate weld or inhibit weld functions are not activated, then the following digital
input signals are tested:
timer_ready
flow_ok
temp_ok
current_ok
In the event of an error, a suitable error text is assigned to the text string errtext.
If timer_ready = 0, then one attempt to reset the timer is made and a new check of the
input is made before an error is indicated.
PROC sw_postweld_sup ()
spotweld postweld supervision
The routine is executed after the weld process before movement to the next position.
If an error text is assigned to the text string errtext, then the system is automatically
stopped with the error text on the display and with a possibility to restart the supervision
routine and continue the program execution.
Default functionality:
The work_select signal is set or reset according to the Retract switch in the instruction.
