1) Use shielded cable for the connections of the potentiometers (especially for the
SP POT). The shielded cable reduces the noise in the wiper voltage. Connect
the shield to a GND pin of the eps-ac0 connectors.
2) Use the FB ENC instead of the FB POT as feedback sensor. The Encoder has
not noise. When the Encoder is stopped in a position, the Encoder counting is
absolutely constant.
3) Reduce the gain of the Closed Loop. It means KP and POS. ACCURACY
parameters must be decreased. When the gain reduces, the modification of the
position error due to noise, are less amplified giving less dither; but less
accuracy is got in the final pursuing at the wished position.
