Variation 1: Line stop signal
Enable pressure build-up feature and select condition for which the
pressure build-up is to be started (here: Line stop signal).
The motors are speed-controlled during production. If the signal Line stop is
switched via the interface Standard I/O or the field bus, the motors are
pressure-controlled to the value Setpoint for pressure build-up.
As soon as the signal Line started is switched, the melter returns to
speed-controlled mode.
