Parameter
Description Data Read/write
P170*
extEnAVWF(aftDP)
170
Function parameter for entering the weighting factor for
the actual position. With the help of the actual-value
weighting factor, the actual position measured can be
converted to another reference system. The parameter
value entered represents the fractional component of the
actual-value weighting factor. The real weighting factor of
the actual value is obtained by adding P169 to
(P170/100000000). The fractional component is entered
to 8 decimal points. The actual-value weighting factor is
thus accurate to 8 decimal places.
Example:
Position-feedback scaling factor: 5.00321
Input P169 = 5, P170 = 00321000
Position-feedback scaling factor: 2.00000123
Input P169 = 2, P170 = 00000123
Position-feedback scaling factor: 0.5
Input P169 = 0, P170 = 50000000
Note:
The following zeroes (P170) must be input.

P171*
Pos Resolution
171
Function parameter for defining the position resolution.
This parameter defines the resolution with which the
position measured at the motor encoder is provided for
further processing. The number of increments is set which
is to correspond to one mechanical revolution. The
squared value is to be entered as the parameter value.
