RC-filter inside the housing of X15
For an application in PUMA the parameter block FFS for frequency output of the
PWM is indicated:
*) This parameter field remains empty.
The carrier frequency is defined in the first line (the parameter Quantity remains
empty, a default value of 10 kHz is defaulted). In the second parameterization
line a speed range of 0 - 10000 rpm is assigned a DC from 0.001 to 90 %. The
value 90 is to be varied according to the mains voltage so that 10 V arise at the
exit.

Information
This kind of the demand value is suitable only for small claims of the default and
to employ only in a closed control loop because of the bad absolute accuracy.
The resolution on the other hand is very high.
