5.1
Pre-selecting a JOB
The PHOENIX has a wide range of adjustable parameters available which are managed using what are
known as JOBs. The corresponding welding task is defined using a JOB. A total of 255 JOBs can be set
(1 to 255).
The JOB pre-selection can only be carried out by the machine if the “Machine JOB pre-selection” bit has
been set (set automatically in some actuation profiles and does not appear in the actuation profile). Only
then can a valid JOB be specified. If the JOB pre-selection is deactivated, a JOB can be specified by the
M31x control unit for the PHOENIX.
JOBs can be pre-selected only when the system is at a standstill (no welding operation). If the
PLC occupies a different JOB number at runtime, however, the set JOB number is stored
temporarily in the module and the switching is carried out when the welding process is ended.
There is no switching if a completed switching has been cancelled again during the welding
process.
5.2 Program
operation
Up to 16 programs can be pre-selected in the PHOENIX. Each program directly specifies an assignment
to a wire feed value, a voltage correction, as well as a dynamic value (PHOENIX) and welding current
and cold wire for TETRIX systems, which are stored in the relevant JOB set on the power source.
Program numbers 1-15 stand for pre-programmed values.
Program 0 is a special case and is intended for what is known as control signal operation. Here the
values for WF, correction voltage and dynamics for PHOENIX systems and for welding current and cold
wire for TETRIX system are specified directly via “analogue” input signals.
If these bytes are assigned other values during normal program operation (1-15), the new parameters are
stored temporarily in the module and transferred to the power source during the changeover to program
0.
The program can only be selected if the “Machine program pre-selection” bit (is automatically set in some
actuation profiles and does not appear in the actuation profile) has been activated.
5.3 JOB
mode
The JOB mode is available as an alternative operating type. In program mode or control signal mode, the
settings for welding type (normal welding/pulses) and operating mode (non-latched/non-latched special)
are carried out via individual actuation signals. In JOB mode these settings are permanently stored in the
power source using program numbers and can be pre-selected directly using those numbers. Every
program is also assigned the superpulse function. The JOB mode is set via the relevant signal and as an
alternative can be permanently set via jumper JP4.
The JOB mode can only be changed when the system is at a standstill.
NOTE
Job mode can also be activated via jumper JP4 if the signal is not included in the data
profile.
