3.2.102 Welding bar control (WELD1)
Purpose
This function block is used for the implementation of a welding bar control.
)
Note!
If you use the function block WELD1:
l Profiles must be created in a relative data model. The data model can be set in
GDC (parameter menu
® basic data dialog).
l Code C1308 must be set to "1".
– If you select a basic configuration with the FB WELD1, C1308 is automatically
set to 1.
– If you select a basic configuration without the FB WELD1, C1308 is
automatically set to 0.

·
Time"
– Welding time in [ms] (1 inc = 1 ms)
·
Distance"
– Option to shift the profile sections 2 and 3 by representing
the parameter WELD1−TIME" (C1445/5) as a distance
(see explanation
^ 3−328).
·
Distance with storage"
– Option to shift the profile sections 2 and 3 by representing
the parameter WELD1−TIME" (C1445/5) as distance.
WELD1−TIME" is kept constant for the further cycle at
the time of transition into phase 2 (see explanation ^
3−329).
