Sinus Incremental Encoder 2 Configuration
0x2213
Description
Defines the resolution of “Sinus Incremental Encoder 2”. The parameter pulses per turn must be set to
the number of pulses per revolution of the connected Sinus Incremental Encoder.
This value multiplied by 2 number of interpolation bits is the total resolution of the Sinus Incremental Encoder.
The values are further limited as follows:
Max. resolution: 2 number of interpolation bits * pulses per turn ≤ 10 000 000
Min. resolution: 2 number of interpolation bits * pulses per turn ≥ 64
