Faults and Alarms
The HPV 900 Series 2 reports two classes of
warnings; these are identified as Faults and
Alarms.
Faults and Fault Annunciation
A fault is 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 whatever 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.
