Parameter Description
P248* BICO parameter for selecting the connector from which
S.DT1 Function the input signal of the DT1 function is to be read in.
248
P249* Function parameter for entering the smoothing time T1 of
DT1 Function T1 the DT1 function.
249
P250* Function parameter for entering the differential time Td of
DT1 Function Td the DT1 function.
250
P251* Function parameter for entering the gain of the band-stop
Band-Stop Gain filter.
251
P252* BICO parameter for selecting the connector from which
S.Band-Stop the input signal for the band-stop filter is to be read in. A
band-stop filter can be used specifically to prevent
252 excitation of mechanical or electrical resonances.
P253* Quality of the band-stop filter
Qty Band-Stop Function parameter for entering the quality of the band-
stop filter. The quality of the band-stop filter indicates how
253 well those parts of the signal which are within the range of
the resonant frequency are filtered out.
P254/P253 yields the width of the frequency range at -3dB
weakening, where:
Lower limit frequency = P254 * [Root (1+ 1/(2*P253)^2) -
1/(2*P253) ]
Upper limit frequency = P254 * [Root (1+ 1/(2*P253)^2) +
1/(2*P253) ]
If a quality of 0.0 is input, the pertinent band-stop filter is
switched off, i.e. it lets all frequencies through.
