Vpn Ripple Lvl
There is normally no need to change this parameter from
the default value. The main circuit DC voltage ripple is
monitored in a cycle of 200 ms. If the difference between
the maximum and minimum values of the ripple exceeds
the value that is set in L8-66 for the number of times that is
set in L8-67, a power supply fault is detected.
