Line Protection Setup
Line Protection: Introduction
The Line Protection Setup wizard sets parameters which affect line protection
functions concerning overfrequency, underfrequency, overvoltage, and undervoltage.
If the Drive Commissioning wizard has been performed, these parameters were setup
automatically. Perform the Line Protection Setup wizard only if you need to restore
these parameters to their original settings or if you need to override the default
parameter settings.

Line Protection: Default Settings
The Line Protection Setup wizard defaults are highly recommended. Making the
default selection will result in voltage and frequency protection settings that are in
line with the specifications of the drive and that are proven settings.

Line Protection: Overvoltage
These parameters set the level of protection of the ac line overvoltage protection. It
is highly recommended to use the control default values as calculated in the previous
steps (you can go backward).

•
Line OV fault level is the ac line voltage above which the AC line over voltage
trip fault occurs.
•
Line OV alarm level is the ac line voltage above which the AC line voltage high
alarm occurs.
•
Line OV alarm clear is the ac line voltage below which the AC line voltage high
alarm goes away.

Line Protection: Undervoltage
These parameters set the level of protection of the ac line undervoltage protection. It
is highly recommended to use the control default values as calculated in the previous
steps (you can go backward).
