Parameter
Description Data Read/write
P180*
AVWF.Num/Denom
180
The parameter defines the actual value weighting factor of
the motor encoder as a fraction with numerator and
denominator. This makes sense with rotational axes
whenever the actual value weighting factor, consisting of
digits before and after the decimal point cannot be
displayed with 8 decimal places.
Parameter P183 is used for selecting between input of the
actual value weighting factor in decimal form with digits
before and after the decimal point and input of a fraction
with numerator and denominator.
Numerator and denominator must satisfy the following
condition:
(((2^P171 * P180.1) mod P180.2) + P180.2) < (2^31 - 1)
One denominator P180.2 <= 2^30 satisfies this.

P181*
extEnAVWF.NumDe
181
The parameter defines the actual value weighting factor
(AVWF) of the external encoder as fraction with
numerator and denominator. This makes sense with
rotational axes whenever the actual value weighting
factor, consisting of digits before and after the decimal
point cannot be displayed with 8 decimal places.
Parameter P166 is used for selecting between input of the
actual value weighting factor for the external encoder in
decimal form with digits before and after the decimal point
and input of a fraction with numerator and denominator.

P182*
S.Angle Pos
182
This parameter defines the source connector for the
position actual value sensing for the motor encoder in slot
C. The connector can be connected both to the rotor
position (KK0090) and to the angle of the machine
encoder (KK0104).
If the motor encoder is a multi-pole resolver and it is also
to be used for referencing with a proximity switch and zero
pulse, KK0096 has to be connected up to position sensing
(P182) instead of KK0090. The multi-pole resolver
supplies quasi Zp zero pulses per mechanical revolution.
The number of pole pairs also has to be taken into
account in the denominator of the IBF factor (P180.2) -
see P109 or the Compendium - in order to compensate
for the higher resolution of KK0096.
