Command Source Setting
5.
Configure the emulated encoder output.
a.
Expand the Settings tree item and open the Encoder Emulation page.
b.
Select 1 - Output - With once per rev index pulse from the Function dropdown list.
c.
Set the Resolution to 2,000 lines/rev.
Note
The encoder resolution output value determines the equivalent resolution of
an incremental encoder in pulses per revolution (PPR). A resolution of 2,000
lines/rev is the same as 8,000 quadrature counts per revolution. You may want to
choose a different value depending on your application needs. In general, higher
resolution values result in more difficult servo loop tuning; lower resolution values
provide less accuracy. If you select a different value for Resolution, remember to
update the Encoder counts per revolution setting in MAX.
d.
Set the Index Offset to 0.
