Starting up the ClipX
Value Explanation
5 Wait for start of zero measurement or limit value undershoot.
6 Wait for the end of the delay zero measurement.
7 Status during zero measurement. When the zero measurement is complete,
the offset is updated.
7.4.2.6 Physical work
The calculation determines the (physical) work over a specific period from the
two quantities of force and distance (or for example torque and angle of rota-
tion). The force must act along the distance. You will need the measurement val-
ues of a different channel for the calculation, e.g. via the ClipX bus.
For Start with define a digital signal that starts the function on a rising edge. At
the start, all output signals are reset to zero. Then the work done since the start
is calculated (∫ F(s) * ds where F = force and s = distance) and outputted in
Work. For Stop with define a digital signal that stops the calculation on a rising
edge. At stop, all output signals are frozen.
Normally, the Work value will steadily increase during the runtime. But if one of
the source signals – that is, either the force or the distance for example –
becomes negative, the work decreases again. In this case Work Max (maxi-
mum work value between start and stop) will have a different value than Work.
Additionally, the maximum force and distance are always calculated and out-
putted during the runtime.
If one of the source signals is invalid, all the output signals will become invalid
as well. The calculation is aborted in this case, and you have to restart it with a
new start signal.
7.4.2.7 Filter
Filters a signal with a Bessel or Butterworth filter. The filters used are 6th-order
IIR filters. The cut-off frequency must be between 0.1 and 100 Hz.
