Analog input signals – signals from the robot to
the welding machine

General

The analog differential amplifier inputs on the interface ensure that the interface
is electrically isolated from the analog outputs on the robot control. Each input
on the interface has its own negative potential.
NOTE!
If the robot control uses only a common GND for its analog output signals,
the negative potentials, i.e., the inputs on the interface, must be linked toge-
ther.
The analog inputs described below are active at voltages of 0 - 10 V. If individual
analog inputs are not assigned (for example, for Arclength correction), the values
set on the welding machine will be used.
