DIGITAL OUTPUTS (signals to Robot).
7.1
Wiring of a Digital Output.
NOTE: If the link between the Power Source and Robot Interface has been interrupted, all digital / analog
output signals will be set to "0" at the Robot Interface.

Pulse Sync (Collision Protection optional) (active high).
Pulse Sync:
Pulse Sync:
Only when "Tig Pulse" process is set, with pulse frequency lower or equal to 10 Hz, the "Pulse Sync"
signal is active and synchronized with every "High Current" pulse.
If the "Tig Pulse" is set the "Pulse Sync" output is active:
− with the pulse frequency lower or equal to 10 Hz the "Pulse Sync" output follows the "High Current"
pulse state.
− with the pulse frequency higher than 10 Hz the "Pulse Sync" output remains fixed at high level.
If the "Tig Pulse" process is not set the "Pulse Sync" output is kept at low level.
The "Collision Protection" signal is available as an option, instead the "Pulse Sync" signal.
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 active signal "Collision Protection".
The Robot Control must initiate an immediate Robot standstill and interrupt the welding process via the
"Quick Stop" signal.
7.3
Power Source Ready (active high).
Power Source Ready:
Power Source Ready:
The "Power Source Ready" signal remains initialised for as long as the Power Source is ready for
welding.
As soon as an error message occurs at the Power Source, or the "Quick Stop" signal is initialised by the
Robot Control, the "Power Source Ready" signal ceases to be applied.
This means that the "Power Source Ready" signal can detect both internal Power Source errors and Robot
errors.
