3.4.23 Mode switching setting (Un\G158, Un\G159)
(1) Set values for the mode desired to be switched to.
(2) After setting the values, turning the operating condition setting request (Y9) from OFF
to ON switches to that mode.

condition setting completed flag (X9) turns OFF.

OFF, turn OFF the operating condition setting request (Y9).
If any value other than the above is written, mode switching is not performed and
only the operating condition is changed.
