Comment on P171:
The value is calculated using the formula:
P171=11+x;
In this case, x=log2 (n/2) with
• x should be rounded-off to the top as integer number
• log2 is the logarithm to base 2
• n is the pole number of the resolver
Comment to IncEncoder.IncResolution:
This value is calculated from P171 using the formula:
IncResolution = 2
(P171–11)
