INTEGRATION GUIDE
6.1.20 Watchdog
This signal function resets a watchdog timer in the robot
interface unit on each transition. The signal takes an
eect when the watchdog function is turned on from
the web user interface or from the setup panel. If the
watchdog functionality is on and the robot can’t maintain
transitioning of this signal, the welding system goes into
an error state. This prevents welding accidents if the robot
loses control over the welding system.
6.1.21 ErrorReset
This signal function resets the ErrorNumber value and the
Error signal to zero on the rising edge of the signal when
there are no active errors in the system. If there are any
active errors, the signal has no eect. The error is active
when the error situation is not resolved.
• 0 = Normal operation
• 1 = Error reset (on rising edge)
6.1.22 HotStartOn
This signal function controls a hot-start on and o, if the
hot-start is enabled to be controlled by a robot from the
web user interface or from the setup panel.
• 0 = Hot start o
• 1 = Hot start on
6.1.23 CraterFillOn
This signal function controls a crater-ll on and o, if the
crater-ll is enabled to be controlled by a robot from the
web user interface or from the setup panel.
• 0 = Crater ll o
• 1 = Crater ll on
6.1.24 DigitalOutput1 – DigitalOutput8
These eight signal functions set digital outputs in an
external I/O device to be active or inactive.
• 0 = Output inactive
• 1 = Output active
6.1.25 WireFeederSelect
This signal function is used to select the wire feeder in a
system that supports two robot wire feeders. The support
of two wire feeders is enabled by installing an extension
kit into the robot interface unit. See the A7 MIG Welder
Operating manual for details.
To be able to select the wire feeder by the means of this
signal, the function must be enabled from the welding
system settings by setting the Wire feeder option to
SELECT AT ROBOT.
• 0 = Wire feeder 1 (the primary wire feeder) is
active.
• 1 = Wire feeder 2 (the secondary wire feeder) is
active.
