Digital input signals (signals from robot)

General remarks

On the OPEN COLLECTOR ROB 5000 OC robot interface, all digital input signals are
inverted (inverse logic).
Wiring of the digital input signals:

Ground: GND = X7/2 or X12/2

Welding start

Signal X2:4
The "Welding start" signal starts the welding process. The welding process continues
until "Welding start" is reset.
Exception:
-
-
Robot ready /
Quick stop
Signal X2:5
„Robot ready" is
-
-
„Quick stop" is
-
-
The "Quick stop" signal stops the welding process immediately
-
NOTE!
The "Quick stop" signal is intended to be used solely as a way of protecting the
machine by shutting it down immediately. If additional personal protection is
required, a suitable Emergency Stop button should be provided.
NOTE!
„Quick stop" ends the welding process without burn-back.
"Quick stop" is active as soon as the power source is switched on

LOW ........ 0 - 2.5 V
HIGH ....... 18 - 30 V
The digital input signal "Robot ready" is not set
The digital output signal "Power source ready" is missing
HIGH active on ROB 4000/5000: 24 V = power source ready for welding
LOW active on ROB 5000 OC: 0 V = power source ready for welding
LOW active on ROB 4000/5000: 0 V = „Quick stop" is set
HIGH active on ROB 5000 OC: 24 V = „Quick stop" is set
