non-welding ready state (e.g.: gun is undocked).
Description
• The system reports a weld error in the last sequence.
• The bit is set instead of the WC at the end of the sequence in the case of
welding errors and is reset when the error is acknowledged.
• The system reports that the selected spot is welded without monitoring and
without readjustment.
• Output is set when:
stepper = off and UI regulation = off
–
(spot usage = Weldjob)
stepper = off AND (spot usage = worldjob AND UI regulation = off OR spot
–
usage = tip check).
(UIP or PSF monitoring = off) and UI regulation = off
(Spot usage = Weldjob)
• The system reports that it will execute a cycle with welding current.
• The bit is continuously updated, even without new spot selection. (derived
from the input "No weld external" and the parameterization).
• With the input "New spot selection", the new spot number is read out, the
corresponding welding program is prepared and the program dependent timer
outputs are set.
• Then the welding timer sets the output "Data for spot selection valid".
• If the robot recognizes the output "Spot selection data valid", it can evaluate
the relevant outputs of the welding timer. In addition, it must remove the "New
data for spot selection" input.
• The welding timer will then remove the outputs "Spot selection data valid" and
"Spot selection valid".
• With the input "New data for spot selection" the selected spot number is called
up in the spot table. If the timer was able to find the spot number in the spot
table, the welding timer sets the output "Spot selection valid".
• The output remains active until the input "Spot selection valid" is cancelled.
• If the selected spot was not found, the output is not set and a corresponding
warning is issued.
• In the detail diagnosis the incorrect selection is displayed.
• Handshake signal to fieldbus input "End of Component".
• Is set after resetting the global actual value counter Q-Stop (component) as
long as input "End of Component" is set.
• If a service program was successfully processed (started via the "Start Service
prorgam" input), this output is set.
• The "Service program WC" output remains active until the "Start Service
program" input is cancelled.
• This output is set at the same time as the weld fault output in the event of a Q
stop fault.
• In the event of a quit error, this output is reset again.
• If the "Query tip state" input is activated, the electrode number whose status is
currently displayed is output, (if the current electrode number = 0, no valid
electrode number is selected.
• If the "Query tip state" input is not activated, the currently activated electrode
number is output as soon as a valid point selection has been made. If the spot
selection is invalid, a 0 is output.
Outputs the number of the active gun (whose data is currently loaded).
