5.2 Status functions

The status functions are bit fields (values) and single bits
(signals) in the I/O table. They are set by the welder system
and read by the robot.

5.2.1 WeldingCurrent
This 16-bit function represents the average welding
current measured during the process. The value is in
scaled or non-scaled mode, depending on the user setup.
In non-scaled mode:
• The minimum value is 0 A.
• The maximum value is 1000 A.
• The minimum step is 1 A.
In scaled mode:
1 1 A
• The minimum value is 0 (0 A).
1 0.1 V
• The maximum value is the
1 which is interpreted as 1000 A.
• The minimum step is 1. The welding current is
calculated from the function value by means of
the value scaling formula.

A3 MIG Welder
• The minimum value is 0 (0.0 V).
• The maximum value is 1000 (100.0 V).
• The minimum step is 1 (0.1 V).
• The minimum value depends on the scaled value
range and is interpreted as 0.0 V.
• The maximum value is the robot scaling
which is interpreted as 100.0 V.
• The minimum step is 1. The welding voltage is
calculated from the function value by means of
the value scaling formula.
