Bulletin 294E
Default Trip Status
On Parameter Sync (PF This fault is generated during the
4M Codes 48, 71 parameter synchronization procedure
and 81) between the Control Module and the
internal drive when the syncing process
fails resulting in the drive configuration
not matching the Control Module
configuration.
On DCBusOrDiscnnct This fault is a result of the drive's Power
(PF 4M Codes 3, 4 Loss (PF 4M Code 3), UnderVoltage (PF 4M
and 5) Code 4) and OverVoltage (PF 4M Code 5)
faults. When an Undervoltage occurs
because the Disconnect has been opened,
the condition will be diagnosed as an
"Open Disconnect" trip
On Stall Trip During starting the motor did not reach
(PF 4M Code 6) running speed within the prescribed
period. This fault occurs when the drive
detects a motor stall condition during
acceleration.
On Over Temperature This fault occurs when the drive detects a
(PF 4M Code 8) heat sink over temperature condition.
On Ground Fault This fault occurs a current path to earth
(PF 4M Code 13) ground has been detected at one or more
of the drive output terminals.
On Restart Retries Drive unsuccessfully attempted to reset a
(PF 4M Code 33) fault and resume running for the
programmed number of auto retries.
On Drive Hardware Fault Failure has been detected in the drive
power section.
On Output Short This fault is generated when a hardware
output short circuit condition is detected.
Off User Defined This fault is generated either in response
to the rising edge of user input 0...5,
[Input00Function...Input- 05Function]
Parameter 58...63.
On Hardware Fault Trip This fault indicates that a serious
hardware problem exists. This fault is
generated when either the PF 4M drive is
not detected or an invalid factory
configuration setting is detected.
In the case of a Disconnect open fault, reclosing the disconnect will cause a reset to be issued.

Description
1. The most common cause of this fault is that the
disconnect has been opened, or that power has
been removed from the drive. To clear the fault,
repower the drive and activate a reset.
2. The drive may have been commanded to default
values. Clear the fault or cycle power to the drive.
1. The most common cause of this fault is that the
disconnect has been opened, or that power has
been removed from the drive. To Clear the fault,
repower the drive and activate a reset.
2. Monitor the incoming line for phase loss or line
imbalance, low voltage or line power interruption.
high line voltage or transient conditions. Bus
OverVoltage can also be caused by motor
regeneration.
3. Extending the [DecelTime1] Parameter 37 or
[DecelTime2] Parameter 70 may also help with this
fault.
1. Check for source of stall (for example, excessive
load, or mechanical transmission component
failure).
2. Increase [AccelTime1] Parameter 36 or
[AccelTime2] Parameter 69 or reduce load so drive
output current does not exceed the current set by
[CurrentLimit] Parameter 31.
Check for blocked or dirty heat sink fins. Verify that
ambient temperature has not exceeded 40° C (104° F).
Check the motor and external wiring to the drive
output terminals for a grounded condition.
Correct the cause of the fault and manually clear.
Check [AutoRestartTries] Parameter 84 and
[AutoRestartDelay] Parameter 85 meets application
needs.
1. Cycle power.
2. Replace unit if failure can not be cleared.
Correct, isolate or remove wiring error prior to
restarting the system.
This fault is generated based on user configuration.
This fault may be reset after the condition that caused
it is removed. For example, the Auxiliary Input goes
low or the DeviceLogix logic drives the bit low.
Power cycle to correct. If fault persists the ArmorStart
LT requires replacement.
