Fault Descriptions

Auto Restart (Reset/Run)
The Auto Restart feature provides the ability for the drive to automatically
perform a fault reset followed by a start attempt without user or application
intervention. This allows remote or "unattended" operation. Only certain faults
are allowed to be reset. Certain faults (Type 2) that indicate possible drive
component malfunction are not resettable. Fault types are listed in the table
Fault Types on page 133. See
information.
Use caution when enabling this feature, since the drive will attempt to issue its
own start command based on user selected programming.

Description
No fault present.
External trip (Auxiliary) input.
Single phase operation detected with
excessive load.
DC bus voltage fell below the minimum
value.
DC bus voltage exceeded maximum
value.
Drive is unable to accelerate or
decelerate motor.
Internal electronic overload trip.
Heatsink/Power Module temperature
exceeds a predefined value.
Control module temperature exceeds a
predefined value.
The drive output current has exceeded
the hardware current limit.
A current path to earth ground has been
detected at one or more of the drive
output terminals.

Action
–
• Check remote wiring.
• Verify communications
programming for intentional fault.
• Monitor the incoming AC line for low
voltage or line power interruption.
• Check input fuses.
• Reduce load.
Monitor the incoming AC line for low
voltage or line power interruption.
Monitor the AC line for high line voltage
or transient conditions. Bus overvoltage
can also be caused by motor
regeneration. Extend the decel time or
install dynamic brake option.
• Increase P041, A442, A444, A446
[Accel Time x] or reduce load so drive
output current does not exceed the
current set by parameter A484, A485
[Current Limit x] for too long.
• Check for overhauling load.
• An excessive motor load exists.
Reduce load so drive output current
does not exceed the current set by
parameter P033 [Motor OL Current].
• Verify A530 [Boost Select] setting.
• Check for blocked or dirty heat sink
fins. Verify that ambient temperature
has not exceeded the rated ambient
temperature.
• Check fan.
• Check product ambient temperature.
• Check for airflow obstruction.
• Check for dirt or debris.
• Check fan.
Check programming. Check for excess
load, improper A531 [Boost Select]
setting, DC brake volts set too high or
other causes of excess current.
Check the motor and external wiring to
the drive output terminals for a
grounded condition.
