Faults
[Fault Alarms 2]
This parameter storesand displays the
last alarm conditions present prior to a
fault.RefertoChapter8forfurtheralarm
information.
A Status description (bit ENUM) is
displayed on line 1 (except Series A
HIMs below version 3.0).
Parameter Number 287
Parameter Type Read Only
[Flt Clear Mode]
This parameter controls the method for clearing faults.
Parameter Number 39

A.
[Ground Warning]
Enables the Ground Warning fault (F57) when the drive
senses ground current in excess of 2 amperes
(approximate). Refer to Chapter 8 for further information.
Parameter Number 204
Parameter Type Read and Write
Factory Default “Disabled”
Units Display Drive
“Disabled” 0 No Fault Generated
“Enabled” 1 Ground Warning Generated
[Phase Loss Mode]
Enables the function that detects a phase loss or the
current rating has been exceeded in the drive if powered
on single-phase line. A fault (F49) or alarm condition will
occur if the DC bus ripple voltage exceeds the level in
[Phase Loss Level].
Parameter Number 330
