Faults
This group of parameters provides information and programmed settings on commonly viewed drive faults.
[Fault Buffer 0-3] Parameter # 86-89 Factory Default None [Fault Buffer 0-3]
Parameter Type Read Only
These parameters store the last (4) faults that occur. If the
same fault occurs multiple times in a row, it will only be
stored once. [Fault Buffer 0] through [Fault Buffer 3] can
only be cleared by ‘‘Reset Defaults” from EEPROM mode
or [Set Defaults] parameter. This will leave a ‘‘F48” in
[Fault Buffer 0]. Units None Buffer 0

Last Fault, stored in EEPROM
Fault from Buffer 0, Stored in EEPROM
Fault from Buffer 1, Stored in EEPROM
Fault from Buffer 2, Stored in EEPROM
[Clear Fault] Parameter # 51 Factory Default ‘‘Ready” [Clear Fault]
Parameter Type Read & Write
This parameter is used to clear a fault and return the drive
to ready status if the fault condition no longer exists.

Units None Displays ‘‘Ready” Display after function complete
IMPORTANT: [Clear Fault] will stop a running drive. Also
[Clear Fault] does not clear [Fault Buffer 0] through
[Fault Buffer 3].
‘‘Clear Fault” Attempts to clear fault
[Cur Lim Trip En] Parameter # 82 Factory Default ‘‘Default Run” [Cur Lim Trip En]
Parameter Type Read & Write
This setting determines whether or not exceeding the

Units None Setting ‘‘Trip @ I Lim” A Diagnostic Current Limit Fault is generated
setting in [Current Limit] will cause a Diagnostic Current
Limit Fault (Fault F36).
‘‘Default Run” No fault generated
[Line Loss Fault] Parameter # 40 Factory Default ‘‘F03 Enable” [Line Loss Fault]
Parameter Type Read & Write
This setting determines whether a 15% drop in DC Bus
