Q-stop Using the "Q Stop" function, the weld timer can detect any
problems occurring in the PSF, UIP or FQF parameters,
which can be signalled to the operator and/or the PLC. With
the help of a program-specific, configurable supervision, it
must first be defined which PSF, UIP and/or FQF values are
to be detected as basically problematic by the weld timer.
The weld timer generally accounts for actual values within the
"conditional tolerance range" of the corresponding monitored
value only. In addition, you have to define the threshold for
the weld timer that has to be exceeded in order to actually
signal the problems occurred as an error. One differentiates
between:
• program-specific Q Stop
• component-specific Q Stop
