Analogue input signals (signals from robot)
General remarks The analog differential amplifier inputs on the robot interface ensure the robot interface
and the analog outputs on the robot control are electrically isolated. Each input on the
robot interface has its own negative potential.
If the robot control uses a common GND for its analog output signals, the negative
potentials, i.e. the inputs on the robot interface, must be linked together.
The analog inputs described below are active at voltages from 0-10 V. If individual ana-
log inputs are not allocated, the values set at the power source will be used.
Welding current
command value
Pin X2/1....... Analog in + 0 to + 10 V
Pin X2/8....... Analog in - (minus)
A voltage of 0 - 10 V is specified for the “Welding current command value”.
0 V ........ Minimum welding current
10 V ...... Maximum welding current
The command value for “Welding current” cannot be entered while in Job mode.
External parame-
ter 1 command
value
Pin X2/2....... Analog in + 0 to + 10 V
Pin X2/9....... Analog in - (minus)
A voltage of 0 - 10 V is specified for external parameter 1.
0 V ........ External parameter 1 - minimum value
10 V ...... External parameter 1 - maximum value
IMPORTANT! The power source operating instructions contain a much more detailed
description of the external parameter, as well as the functions it can perform.
Base current
command value
Pin X14/3....... Analog in + 0 to + 10 V
Pin X14/11......Analog in - (minus)
A voltage of 0 - 10 V is specified for the “Base current command value”.
0 V ........ Minimum base current
10 V ...... Maximum base current
Duty cycle com-
mand value
Pin X5/1....... Analog in + 0 to + 10 V
Pin X5/8....... Analog in - (minus)
A voltage of 0 - 10 V is specified for the “Duty cycle command value”.
0 V ........ Minimum duty cycle
10 V ...... Maximum duty cycle
