ANALOG INPUTS (signals from Robot).

6.1

Wiring of an Analog Input.

The analog differential amplifier inputs on the Robot Interface ensure that the Robot Interface has an high
impedance versus the analog outputs of the Robot Control.
Each input on the Robot Interface has its own negative potential.
If the Robot Control only has one common Gnd for its analog output signals, then the negative potentials
of the inputs on the Robot Interface must be linked to one another.
The analog inputs described below are active with voltages of 0 to +10 V.
6.2

Welding Current.

Welding Current:
Welding Current:
The "Welding Current" command value is defined with a voltage of 0 ÷ 10 V:
0 V = 0 A;
10 V = 500 A.
To allow the setting of "Welding Current" function from Robot Control the dip - switch DIP3-1 on Robot
Interface must be set OFF (par. 3.5.2).
If dip - switch DIP3-1 is set ON, the "Welding Current" function is disabled.
The "Welding Current" signal can only be defined if the "Job mode" has been selected.
NOTE: In "Tig mode" minimum and maximum values are saturated to the minimum and maximum
welding current related to the Power Source connected (e.g.: on art. 353 minimum value is 5 A in
Tig DC, 10 A in Tig AC and maximum value is 450 A).
6.3

Wire Speed.

Wire Speed:
Wire Speed:
The "Wire Speed" command value is defined with a voltage of 0 ÷ 10 V:
0 V = -2.5 m/min.
10 V = +10 m/min.
To allow the setting of "Wire Speed" function from Robot Control the dip - switch DIP3-2 on Robot
Interface must be set OFF (par. 3.5.2).
If dip - switch DIP3-2 is set ON, the "Wire Speed" function is disabled.
The "Wire Speed" signal can be entered only in "Tig" mode and if the "cold-wire" process is enabled
from the Control Panel. This regulation refers to the "high" speed of the motor during the "cold-wire"
process.
