Calculating P-0-0523,

Commutation setting measured

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

(see "Calculation formulas for P-0-0523" and table "Motor constant

for commutation setting").
