There are four means of fault annunciation: 

 

Two classes of warnings are reported by the 
Drive; these are identified as Faults and 
Alarms. 
An Alarm is a drive condition worth noting that 
may or may not require immediate attention, 
but the condition is not severe enough to stop 
operating the drive.  In many cases, Alarms 
will automatically clear when the condition 
returns to normal or when the drive is stopped 
and restarted. 
Faults and Fault Annunciation 
A Fault is a severe failure condition 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. 

1.  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.  Setting PRIORITY MESSAGE (C1) to 
DISABLE can disable priority Messages. 
 
2.  The fault will be placed on the active fault 
list which will record and display currently 
active faults.  The faults will remain on the fault 
list until an active fault reset is initiated.  The 
drive will  

not be able to run until all active faults are 
cleared. 
 
 
 
 
 
 

 
 
 

3.  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.

Fault Clearing 
Performing a fault reset can clear most faults.  
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 could immediately go into 
a run state.  However, if the auto-fault reset 
function is enabled (FAULT RESET 
SRC(C1)=automatic) then the run command 
needs to be cycled. 
 
A fault reset can also be performed manually 
via the Digital Operator.
