I am still confuse to connect encoder CUI AMT102 V to G320X, correct me if wrong what I will do are as follows:

The procedure for connecting encoder CUI AMT102 V:
1. Determine the optimal encoder line count (45kHz / 40) / 4 = 281.25 equal to 256 count, starting from low value?
2. Set encoder resolution on DIP switch to 0011 = 256
3. SWITCH FUNCTIONS:

a. SW1 Not used
b. SW2 “ON” and SW3 “ON” = Step pulse times 1 (default)
c. SW4 “ON” and SW5 “ON” = +/- 256 count following error limit (default)
d. SW6 “OFF” = Default
e. SW7 “OFF” = Use LIMIT trimpot setting only (default)
f. SW8 “ON”, SW9 “OFF”, SW10 “OFF” = Medium gain 1 (default)

4. Connect the encoder power supply ground to this terminal.
5. Connect the encoder +5VDC to this terminal
6. Connect the encoder channel “A” to this terminal
7. Connect the encoder channel “B” to this terminal

Thanks.

This looks like a good start. Once you get it running, you
may be able to bump the resolution some depending on
your computer speed, and the stability of your machine.

Steve,
Thanks for your comment. What is the reason to set encoder resolution higher? How much max encoder resolution? I got my PC with I5.

The reason for setting a higher encoder resolution on a servo
system would be to get higher resolution of movement in the
machine.

Unlike using microstepping with a stepper motor, there is
usually no advantage in terms of motion smoothness, and
there may be a penalty in speed if your computer cannot
generate step pulses fast enough for the higher resolution.

You should make a reasonable decision about what your
machine can achieve in terms of accuracy and resolution,
and set your encoder resolution accordingly. Excess
encoder resolution will cause your computer to work
harder without achieving any useful improvement in the
actual cuts that result.
