5.6.2: Rotary Motor Feedback Setup Options
5.6.2.1 Click the Feedback tab.
5.6.2.2 As appropriate for each encoder or resolver, enter the options described here.
Feedback Type Options/Actions
Incremental In the lines field, enter the number of encoder lines (see encoder or
motor data sheet). As indicated by the counts field, the number of
encoder counts per revolution is equal to 4 x the number of lines.
Analog In Fundamental Lines, enter the number of fundamental encoder lines
(see encoder or motor data sheet). As indicated by the Fundamental
Counts field, the number of fundamental encoder counts per revolution is
equal to 4 x the number of Fundamental Lines.
Optionally modify the encoder resolution by changing the Interpolation
value. The interpolated resolution (Interpolated Counts Per Rev) is the
product of Fundamental Counts value and the Interpolation value.
Resolver
Optionally modify the feedback resolution by changing the value in
Counts Per Rev. Default: 16384.
5.6.2.3 If two feedback devices are installed, verify that the values of Motor Turns to Position
Turns correctly represent the ratio of motor encoder turns to position encoder turns.
5.6.2.4 If using a brake, then proceed to Brake/Stop (Optional) (p. 91).
Else, proceed to Calculate (p. 92).
5.6.3: Linear Motor Feedback Setup Options
5.6.3.1 Click the Feedback tab.
5.6.3.2 As appropriate for each encoder installed, enter the options described below.
Feedback Type Options/Actions
Incremental Choose units (mm, nm, um) and then enter the Encoder Resolution
(see encoder or motor data sheet).
Analog Enter the Fundamental Pitch (distance between encoder lines; see
encoder or motor data sheet). As indicated by the Fundamental
Resolution field, every unit of fundamental pitch produces four encoder
counts.
The interpolated resolution is the dividend of Fundamental Counts
value/Interpolation value. Optionally modify the resolution by changing
the Interpolation value.
Low Frequency Analog
(Normally used with ServoTube) Pole Pitch is the distance between
poles in a poll 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 um. Optionally modify the resolution by changing the
Counts/Pole value.
Click Restore Default to restore default Counts/Pole.
5.6.3.3 If using a brake, then proceed to Brake/Stop (Optional) (p. 91).
Else, proceed to Calculate (p. 92).
