confirm and push ESC more times to get the home position.
PID parameters set and modifications (see table below):

Push Enter button, on the green display Opr appears; using the down arrow, scroll until group PArA is reached and
push Enter.

on the green display Pb1 e appears and on the red one the set parameter.

Push is sequence the down or up arrow the menu is scrolled.

Push Enter to select and the arrows to choose the desired value. Enter to confirm.
