Machine parameters for the axes and spindles.
NORBWIDTH
Normal bandwidth.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drive, Sercos and simulated.
Possible values: From 0 to 100.0
Default value: 1.0
Associated variable: (V.)[ch].MPA.NORWIDTH[nb].xn
Parameter included in the FILTER table.
This parameter is calculated with the following formula. The f1 and f2 values correspond to
the break frequency where the amplitude drops 3 dB or it reaches 70% of the nominal
amplitude.
-3 dB = 20 log (A/Ao) ==> A = 0,707 Ao
SHARE
Percentage of signal going through the filter.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drive, Sercos and simulated.
Possible values: From 0 to 100.
Default value: 100.
Associated variable: (V.)[ch].MPA.SHARE[nb].xn
Parameter included in the FILTER table.
This parameter indicates the percentage of signal going through the filter. This value must
be equivalent to the percentual overshooting of the resonance because it must compensate
for it.
WORK SETS.
NPARSETS
Number of parameter sets available.
Parameter valid for linear and rotary axes and spindles.
Parameter valid for analog drive, Sercos and simulated.
Possible values: From 1 to 4.
Default value: 1.
Associated variable: (V.)[ch].MPA.NPARSETS.xn
Up to 4 different parameter sets may be defined to indicate the dynamics of the axis in each
one of them (feedrates, gains, accelerations, etc.).
