Description
• With a rising edge on this input, the global actual value Q stop
(component) counter is reset.
• Handshake signal: Fieldbus output "Acknowledgement end of
component"
• With this signal the selected service program is started.
• A previous spot selection is not necessary for this.
• The successful processing of the service program is indicated by the
service program weld complete.
• The selected point is executed in Ghost Run mode.
• All times are taken over from a welding program to be executed with
ignition switched off and a global programmable force value is set.
• After execution of a sequence without ignition, with the "Ghost Run"
signal set, all wear counters are incremented as for a sequence with
ignition.
• After the weld, the output continuation contact is set.
• CAUTION: The system operator must ensure that the wear counter
corresponds to the actual cap condition of the electrode by milling the
electrodes after Ghost Run operation has ended.
• Otherwise, problems with readjustment (KSR operation) and dynamic
tolerance bands (UIR operation) may occur.
• If the "Weld release IO field bus" input is not set, an error message
"Start without external weld release" is issued when a sequence is
started and the sequence is not started.
• However, the error is not triggered if the start comes from the user
interface via the start simulation.
• If the input is removed during a sequence, the sequence is still
executed to the end without an error message.
• The error is not self-acknowledging.
• It must be reset via the input or the command "Reset fault" or "Reset
fault with WC".
• A reset via the input or the command "Reset fault with reweld" is only
accepted by the controller if the input "Weld release IO field bus" is
set.
• If the input is missing, neither the additional sequence is started nor
an error is deleted.
• The robot selects one of 1...255 possible vehicle types.
• This represents an extension of the spot selection.
• Select the spot number. Spots of the spot table are composed of the
type ID (Extension1) and the spot number.
• "Wild Card":
No wild card rule applies.
The selection of spots must be done explicitly.
(Vehicle type and spot number must both be present) otherwise a
spot selection error will occur.
• The service spot numbers are in the range from 1100 to 2199 and are
permanently assigned in the application. The service spot numbers,
like the associated WeldJobs, are absolutely necessary for operation.
(if necessary, suitable import files must be created)
• A spot with the spot number "0" (regardless of the selected type ID) is
an invalid point and will not be loaded or evaluated. No spot selection
error is generated in this case.
• If a welding process is started on spot "0", this does not lead to any
gun movement and the process is aborted with error.
