Information on this product
- UIR (adaptive controller; optional)
PHA and KSR control modes can be separately configured for each
weld time (mixed operation). UIR only in MainWLD.
• Current monitoring:
-
Reference currents can be programmed independent of the regu­
lation command values
- Tolerance band in percent, with asymmetric programming capab­
ility
- Standard or mixed mode (mixed mode: monitoring can be sepa­
rately configured for PreWLD, MainWLD and PstWLD).
• Automatic spot repetition if current was too low
• Time monitoring
• Electrode management:
-
Management of up to 31 electrodes (number dependent on type
of timer)
- Stepper function for %I (%I stepping)
- Electrode tip dressing including initial dressing
- Stepper function for pressure (electrode force stepping)
- Warning table with graphic representation of electrode wear
• Generating the gun force:
-
Programming the force in kN for each welding program
- Output as analog (voltage, current) and/or digital actuating vari­
able (depending on timer type)
- Analog or digital feedback (depending on timer type)
- Force calibration for adjustment of the actuating variable to the
actuators used
• Pressure profile:
-
up to 10 different electrode forces can be programmed during a
program schedule
• Freely programmable output: (depending on timer type):
up to 3 different on/off times during a program schedule can be pro­
grammed. Serves e.g. for controlling a back-pressure control valve
or generally for triggering further processes.
• Calibration:
-
for current (to adjust the welding equipment to an external refer­
ence ammeter)
- for force (to adjust the electrode force to an external reference
force meter)
• Logging functions (ISO 9000):
-
Fault/event log
- Weld fault protocol
- Data change protocol
- Welding current log
• integrated diagnosis memory
• Fault allocation:
-
certain process errors/faults can be programmed as “faults” or
“warnings“
• Status display of I/O signals in online mode
• %I correction:
-
program-specific input
- electrode-specific input
