IDN 117 (S-0-0117) Resolution of Rotational Feedback 2
(External Feedback)
The resolution of the rotational feedback 2 contains the cycles per revolution of a rotary encoder as an external feedback ( IDN 53 ). The resolution of the external position feedback depends on this parameter and the multiplication factor 2 ( IDN 257 ).
The resolution could be calculated with the following calculation rule: resolution = external feedback (IDN117) x 4 x multiplication factor 2 ( IDN 257 ).
The maximum resolution is set within IDN 79 divide by 4, the drive checks during runup, that the setting will not give a bigger value. In this case the drive automatically calculates a new multiplication factor 2 ( IDN 257 ).
