DIGITAL INPUTS (signals from Robot).

5.1

Wiring of a Digital Input.

5.1.1 Characteristics.
Signal low logic level
high logic level
Reference potential:
5.2

Arc On.

Arc On:
Reference potential:
"Arc On" signal is active high, and starts the welding process.
As long as the "Arc On" signal is present, the welding process remains active.
Exception:
- the digital input signal "Robot Ready / Quick Stop" is absent.
- the digital output signal "Power Source Ready" is absent (e.g.: overtemperature, insufficient water,
etc.).
NOTE: When Robot Interface is plugged-on, the Power Source is automatically set in the 2-step mode.
5.3

Robot Ready / Quick Stop.

Robot ready / Quick Stop:
Reference potential:
"Robot Ready" signal is active high:
- +24Vdc is required in order for the Power Source to be ready for welding.
"Quick Stop" is active low:
- +24Vdc absent "Quick Stop" signal is initialised.
The Robot Control sets this signal as soon as it is ready to weld.
"Quick Stop" signal stops the welding process immediately, without "Burn-back".
The warning message "rob" blinking is displayed on the Control Panel.
NOTE: If the "Robot Ready" signal has not been set, none of the commands will function.
WARNING ! The "Quick Stop" signal is exclusively provided as quick stop to protect the
machine. If an additional protection of persons is requested, still use an
appropriate emergency stop switch.
After the Power Source is switched on, "Quick Stop" signal is active immediately:
- the warning message "rob" blinking is displayed on the Control Panel.
- making the Power Source ready for welding deactivate the "Quick Stop" signal (initialise "Robot
Ready").
