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:
- ROB 4000/5000 to 24 V (High)
- ROB 5000 OC to GND (Low)
Parameters Signal level:
- LOW ........ 0 - 2.5 V
- HIGH ....... 18 - 30 V
Ground: GND = X7/2 or X12/2
Welding start
ROB 4000/5000 ROB 5000 OC
Signal X2:4 HIGH LOW
The “Welding start” signal starts the welding process. The welding process continues
until “Welding start” is reset.
Exception:
- The digital input signal “Robot ready” is not set
- The digital output signal “Power source ready” is missing
Robot ready /
Quick stop
ROB 4000/5000 ROB 5000 OC
Signal X2:5 HIGH LOW
„Robot ready“ is
- 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
„Quick stop“ is
- LOW active on ROB 4000/5000: 0 V = „Quick stop“ is set
- HIGH active on ROB 5000 OC: 24 V = „Quick stop“ is set
The “Quick stop” signal stops the welding process immediately
- The “St | oP” error message appears on the control panel
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
