Perunit Motor Voltage
[Motor Volt Fdbk]
Displays the perunit value of motor voltage
as determined from an analog–to–digital
converter input. This data is scaled to read
1.0 pu at rated motor voltage. This is a
version of parameter 265 that has been
scaled to perunit to be compatible with
analog outputs. This data is averaged and
updated on a 50 millisecond basis.
