The electrode status outputs and the acknowledgement inputs (tip dressing, tip
change) refer to the electrode that has been assigned to the currently selected
program. Acknowledge tip dressing or Acknowledge tip change for electrode 0
applies to all electrodes.
A handshake is also provided for electrode maintenance as a precaution. The
timer signals the electrode status of the current electrode gun using specific
outputs. The robot can influence the internal tip dress and wear counters at any
time using the "Tips have been dressed" and "Electrodes have been replaced"
outputs. In order to enable the robot to safely verify that receipt of these
acknowledgments has been safely detected, the two inputs are looped through
again to the "Tips have been dressed detected" and "Electrodes have been
replaced detected" outputs.
The "End of stepper" output becomes high whenever a stepping cycle is
exceeded.
A group message is output for all electrodes via the electrode status outputs if a
program has been selected to which electrode 0 has been assigned.
A separate log is maintained for the electrode changes.
A second independent prewarning output can be set, to show, that the electrode
may be changed.
A second independent tip dress request output can be set, to show, that the
electrode may be dressed.
7.1.4
Dressing tool change
The timer has additional counters that count each tip dress performed on each
electrode. If a counter exceeds a programmed prewarning value, the
„ Prewarning dressing tool" output will be set. When the programmed maximum
value is reached, the „ End of stepper dressing tool" output will be set.
The function is switched off if the value „ 0" is specified as maximum value.
Using the "Acknowledge, tip dressers changed" input, the dresser counts can be
reset. In order to enable the robot to safely verify that receipt of these
acknowledgments has been safely detected, this input is looped through again to
the "Acknowledge, tip dressers changed" output.
Using the "End of stepper" output, a group message is output for all tip dresser
blades if a program has been selected to which electrode 0 has been assigned.
A separate log is maintained for tip dresser blade changes.
7.1.5
Pressure control valve
The pressure control valve may be optionally checked at the end of the squeeze
time.
7.1.6
Gun Force selection
The absolute value output here corresponds to the value stored in the timer. The
range of values is specified externally.
