Special features

The welding controller features the following specifics:
• Control will be networked a Profinet assembly.
• Q-Stop
The timer support the Q stop function of the UI controller firmware (since
version -404).
Via the input „End of component quality logic" the component-specific counter
for the Q stop logic will be reset.
• Acknowledge spot selection
The spot selection are mirrored via the outputs, as soon as the selection has
been processed, that means the pressure outputs and the electrode state
outputs follow the selection.
• Number of electrodes: 10 (electrode no.: 0 to electrode no.: 9)
• The time within the current has to exceed a minimum threshold is adjustable. If
this threshold is not exceeded on average, the sequence is stopped and an
error message occurs.
• A verification of the pressure control valve at the end of the squeeze time can
be selected.
• The "Stop circuit open / no 24 V" fault is automatically reset.
• The DC link voltage is always verified, the fault message is automatically reset.
• Due to timer-internal routines, the minimal preweld/squeeze time is 16 ms.
• The target electrode force is installed via 8 bits of the serial I/O array.
Value range: 0 to 255; the valency per increment is programmable (default: 100
Newton/inc).
• With spot addressing ( spot selection + ident) via 24 Inputs
If the spot selection + ident "0-0" is selected, will be automatically the program
"0" selected and the in this program defined pressure (default = 0) set.
• State of input "Start recording protocol" is registered in weld current log.
