2.27.5 Control information

Control information from the robot to the welding system is transmitted as parameters and individual bits (signals) in
the fieldbus control table.

Description
Controls the active memory channel.
Sets the welding travel speed of the robot for heat input calculation
shown in AX Manager.
Description
Controls the welding cycle. In the simulation mode, this con-
trols the simulation cycle.
Turns the simulation ON and OFF.
Note: The arc parameter must be set to 'Select at robot' in AX
Manager (refer to "Robot settings" on page 125).
Drives the filler wire forward. The wire feed speed is 1.0
m/min for 3 seconds, after which the speed is 5.0 m/min.
Drives the filler wire backwards. The wire feed speed is 1.0
m/min for 3 seconds, after which the speed is 5.0 m/min.
Controls the shielding gas valve. The gas valve can be con-
trolled during welding but not during simulated welding.
Controls the compressed air valve. The air valve cannot be
controlled during welding or simulation.
Controls the choice of whether the filler wire or gas nozzle is
used for touch sensing.
Note: The touch sensor tool must be set to 'Select at robot' in
AX Manager (refer to "Robot settings" on page 125).
Sets the touch sensor power source and the touch tool on.
The touch sensing voltage depends on the user settings in
AX Manager (refer to "Robot settings" on page 125).
Resets the ErrorNumber value and the Error signal to zero on
the rising edge of the signal when no errors are active in the
system.
Resets the watchdog timer in the system on each watchdog
bit transition. If the watchdog timer is not reset in 0.5 s inter-
vals, the welding system gives a watchdog error. To enable
generation of watchdog errors, the watchdog parameter
must be set to ON in AX Manager (refer to "Robot settings"
on page 125). The bit is also provided as a loopback bit back
to the robot (if available in the fieldbus control table) even
when the watchdog parameter is OFF.
Sets the digital output active or inactive.
To use digital outputs 1...8, the DIO (Digital Input/Output)
card must be installed in the add-on card slot 1.
To use digital outputs 9...16, the DIO card must be installed
in the add-on card slot 2.
