4. Use the Increment or Decrement key to scroll through the Control
Status options until Fault Queue is displayed.
5. Press the Enter key.
6. Press the Enter key when View Queue is displayed.
The fault queue can contain up to 32 faults. The 1336 IMPACT drive
reports the faults using the following format:
I n v O v e r T e m p T r p
F 2 0 2 8 T r i p 1
Fault name
Fault queue
indicator
Fault code
number
Trip indicator
Position in
fault queue
The trip indicator is only present if this fault caused the drive to trip.
The last number (1) indicates the position of this fault within the
fault queue.
A marker is placed in the queue when the first fault occurs after a
power up sequence. This power up marker is as shown.
P w r U p M a r k e r
F 0 11
The 1336 IMPACT drive tracks the time that has elapsed since
power up. The drive uses this information as a time stamp so that
you can tell when a fault occurred in relation to when the drive was
powered up.
To clear the fault queue, select Clear Queue from the Fault Queue
options.
To view the warning queue, select Warning Queue from the Control
Status options. The remaining steps are the same as for the fault
queue.
When a fault occurs, the fault is displayed until you initiate a Drive
Reset or a Clear Faults command. A Drive Reset clears all faults,
while a Clear Faults command only clears soft and warning faults.
You can perform a Drive Reset and Clear Faults either through bits
in Logic Input Sts (parameter 14) or with a terminal.
