Troubleshooting
Faults and Alarms
Two classes of warnings are reported by the
HPV 600; these are identified as Faults and
Alarms.
Faults and Fault Annunciation
A fault a severe failure that will stop a drive if it
has been running and prevent the drive from
starting as long as it is present. All faults require
some type of action by the user to clear.
There are four means of fault annunciation.
A priority message will be seen on the Digital
Operator:
A priority message will overwrite what ever is
currently displayed. The user can clear this
message by pressing any key on the Digital
Operator keypad. If another fault is present, the
next fault will appear as a priority message.
NOTE: Clearing the fault priority message from
the display DOES NOT clear the fault from the
active fault list. The faults must be cleared by a
fault reset before the drive will run.
The fault will be placed on the active fault list.
The active fault list will display and record
currently active faults. The faults will remain on
the fault list until an active fault reset is initiated.
The fault will be placed on the fault history. The
fault history displays the last 16 faults and a time
stamp indicating when each happened. The
fault history IS NOT affected by an active fault
reset or a power loss. The fault history can be
cleared via a user initiated function.
The user can assign a fault to an external logic
output.
Fault Clearing
Most faults can be cleared by performing a fault
reset. The fault reset can be initiated by:
an external logic input
the serial channel
automatically by the drive
CAUTION
If the run signal is asserted at the time of a fault
reset, the drive will immediately go into a run
state.
CAUTION
If the run signal is asserted at the time of a fault
reset, the drive will immediately go into a run
state. Unless using the auto-fault reset function
(FAULT RESET SRC(C1)=automatic) then the
run command needs to be cycled.
A fault reset can also be done via the Digital
Operator.
