Faults
[Fault Alarms 2]
This parameter stores and displays the
last alarm conditions present prior to a
fault. Refer to Chapter 7 for further alarm
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
Parameter Type Read and Write
Factory Default “Enabled”
Units Display Drive
“Disabled” 0 Faults cleared only by cycling power
“Enabled” 1 Faults cleared by issuing a valid stop
command (only through TB3/HIM) or
cycling power - see Bit 3 of the Logic
Control Structure in Appendix A.
[Ground Warning]
Enables the Ground Warning fault (F57) when the drive
senses ground current in excess of 2 amperes (approxi-
mate). Refer to Chapter 7 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
Parameter Type Read and Write
Factory Default “Disabled”
Units Display Drive
“Disabled” 0 No Fault Generated
“Alarm” 1 Generates a Phase Loss Alarm
“Fault” 2 Generated F49 Input Phase Fault
[Phase Loss Level]
Sets the DC bus ripple voltage above which a phase loss
fault/alarm will occur. The sensitivity for detecting a blown
fuse on a three-phase system can be increased by
lowering the setting for this parameter.
Parameter Number 331

[Precharge Fault]
Enables or disables the Precharge Fault, which indicates
insufficient DC bus charging 20 seconds after power-up.
Parameter Number 332
Parameter Type Read and Write
Factory Default “Enabled”
Units Display Drive
“Disabled” 0 No Fault Generated
“Enabled” 1 Precharge Fault Generated
[Motor OL Ret] – Firmware 6.001 & later
When enabled, the accumulated motor overload count will
be stored on power-down and restored on power-up. From
that point, normal overload operation continues. When the
value is changed from enabled to disabled the motor
overload count will be reset to 0.
Parameter Number 379
