Permanently configurable standard signals
A series of signals can be permanently set using plug-in jumpers to reduce the amount of wiring work and
in case a specific configuration is to be used. Alternatively, these signals can be actuated via external
signals if the relevant jumper is not plugged in.
5.3.1
Enable start
To increase the safety of the system, a running process can be interrupted immediately by stopping the
enable signal. This is especially important in complex program sequences where merely stopping the
start signal would cause the process to stop but would not immediately interrupt the system. In this case,
the system also reports an error.
The enable signal can be set as a fixed value by setting jumper JP6. The control is thus ready for
operation immediately each time the welding system is switched on (main switch).
With the EWM Config Tool the function of the signal can be changed so that the RINT X12 is completely
neutralised when the signal is stopped, i.e. all prioritisations of control signals are stopped, for example.
JP6
Operating mode
-
RINT X12 only reacts to a start signal if signal X10/3 is set.
X
Start signal is always accepted; signal X10/3 is not required.
5.3.2
Control voltage active
For operation with nominal values via analogue control voltages, jumper JP7 can be set as a fixed value.
This enables control signal operation to be set permanently without external wiring (except for analogue
voltages).
Alternatively, the signal can also be actuated by an external signal:
JP7
Operating mode
-
No external control signals are accepted except when
overriding with the X10/4 signal (factory setting).
X
External control signals are always accepted, an external
X10/4 signal is not required.
5.3.3
Inching mode
Two different welding wire inching modes are available which can be pre-defined on the RINT X12 by
means of jumper JP8.
Alternatively, the signal can be activated by an external signal:
JP8
1)
Operating mode
-
Inching is performed by means of a ramp function
2)
. This function
can be overridden by the external X10/9 signal.
(factory setting)
X
Inching is always performed at a constant speed
3)
, no external
X10/9 signal required.
1)
The constant inching speed can be reconfigured with the EWM Config Tool to enable setting the speed
based on the WF specification (control voltage).
This mode is available in the MAG system operating mode only.
2)
The wire is inched for 2 seconds continuously at 1 m/min and then moved at 6 m/min for 6 seconds.
Inching speed then remains at this final value.
The final value depends on the cold wire drive used.
(3)
The wire is moved continuously at 3 m/min.
