Fine resolution external encoder [335] (only SBM2)
If the external encoder is assigned to position detection
on the motor side (P182 = 104), parameterization of
the position detection on the motor side (actual value
evaluation factor IBF P169/P170, resolution P171, IBF
numerator/denominator P180 to FD330) is used for
calculating the zero offset in LU. Otherwise the
corresponding parameter of the external position
detection (actual value evaluation factor P152/P153,
resolution P154 , IBF numerator/denominator P180 to
FD335) is used for this purpose.

The encoder connection may neither be closed nor removed when live!
The converter must be de-energized (24 V electronics power supply disconnected and DC link
fully discharged)!
