The input value in P-0-0523 required for determining the commutation
offset must be calculated from the measured relative position of primary
part with regard to secondary part (see fig. "Measuring the relative
position between primary and secondary part", distance d, e, f or g,
according to possibility of access), as well as a motor-dependent constant
k
mx
(see "Calculation formulas for P-0-0523" and table "Motor constant
k
mx
for commutation setting").

Note:
When determining
P-0-0523, Commutation setting
measured value
you have to make sure the preceding sign is
correct.
If P-0-0523 is determined with a negative sign, this has to be
entered!
