12 DIGITAL SIGNALS FROM POWER
SOURCE TO ROBOT-PANTOGRAPH
CONTROL.
Digital output signals information is updated
every 10 msec both in the Main Page and in the
Log Page.
12.1 Communication Ready (MIG-TIG).
Green light indicates function active.
When active it indicates that the communication
between Robot-Pantograph Control and Power
Source is correctly working.
12.2 Power Source Ready.
Green light indicates function active.
The "Power Source Ready" signal remains
initialized for as long as the Power Source is
ready for welding/cutting.
As soon as an error message occurs at the Power
Source, or the "Quick Stop" signal is initialised
by the Robot-Pantograph Control, the "Power
Source Ready" signal ceases to be applied.
This means that the "Power Source Ready" signal
can detect both Power Source errors and Robot-
Pantograph errors.
12.3 Current Flow.
Green light indicates function active.
The "Current Flow" signal is initialised as soon
as there is a stable arc after the beginning of arc
ignition.
12.4 Process Active.
Green light indicates function active.
When the Robot-Pantograph Control initialises
the "Arc-on" digital signal, the welding/cutting
process begins with the gas pre-flow, followed by
the welding/cutting operation itself and then the
gas post-flow.
From the beginning of the gas pre-flow until the
end of the gas post-flow, the Power Source
initialises the "Process Active" signal (fig. 5).
The "Process Active" signal helps to ensure
optimum gas shielding by ensuring that the
Robot-Pantograph dwells sufficiently long at the
beginning and end of the weld seam or cut.
12.5 Main Current.
Green light indicates function active.
NOTE: As long as the "rob On" is selected on
Control Panel,
automatically remains selected (display
shows: 2-step mode).
3.300.125-C
the "2-step mode"
The following are defined in the Power Source
set-up menu (see Control Panel Instruction
Manual):
- HSA (Hot Start): starting current phase, with
Starting Current, Starting Current Duration
and Slope.
- CrA (Crater Arc): final current phase, with
Final Current, Final Current Duration and
Slope.
Between starting and final current phases, "Main
Current" signal is initialised (fig. 5).

12.6 Collision Protection (MIG).
Green light indicates function active.
In most cases, the Robot torch has a cut out box.
In the event of a collision, the contact in the cut
out box opens and triggers to low the "Collision
Protection" signal.
The Robot Control must initiate an immediate
Robot standstill and interrupt the welding process
via the "Quick Stop" signal.
12.7 Sticking Remedied (MIG).
Green light indicates function active.
If the welding operation does not finish correctly,
the wire may melt to the workpiece.
This situation is recognised by the Power Source
("Sticking Remedied" signal low) and the
"Power Source Ready" signal is cancelled.
"Sti" warning indication is flashing on display
"O" of the Control Panel.
Cut out the wire from workpiece, then set
"Source Error Reset" signal high at least 200 ms.
Once the wire has been detached from the
workpiece and the error has been acknowledged,
