Power Supply Fault
Detection Selection
Vpn Ripple Sel
0: Disabled
1: Coast to Stop
2: Alarm Only
There is normally no need to change this parameter from
the default value.
Monitors the ripple of DC BUS voltage and detects Input
Power Supply Fault(PF2) when the ripple is too bad.

Detection Voltage
Level
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.
