5.6: Feedback Parameters, Linear
As appropriate for each encoder installed, enter the parameters described below. Options
vary with amplifier model.

Type
Parameters/Actions
Incremental
Choose units and then enter the Encoder Resolution (see encoder or motor data sheet).
Enable Encoder Loss Detection and/or Index Loss detection if desired.
Analog
Enter the Fundamental Pitch (distance between encoder lines; see encoder or motor data
sheet). As indicated by the Fundamental Resolution field, Fundamental Pitch divided by
four gives Fundamental Resolution. The interpolated resolution is the dividend of
Fundamental Resolution value/Interpolation value. Optionally modify the Interpolated
Resolution by changing the Interpolation value.
Low
Frequency
Analog
Normally used with ServoTube, Pole Pitch is the distance between poles in a pole pair, as
entered in the Magnetic Pole Pair Length field on the Motor tab. The interpolated resolution
is the dividend of Pole Pitch/Counts per pole value, expressed in micrometers. Optionally
modify the resolution by changing the Counts/Pole value. Click Restore Default to restore
default Counts/Pole.
