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 145 . See Fault Descriptions on page 147 for more
information.
Use caution when enabling this feature, since the drive will attempt to issue its
own start command based on user selected programming.
Fault Descriptions
Fault Types, Descriptions and Actions
No. Fault Type (2) Description Action
F000 No Fault – No fault present. –
F002 Auxiliary Input 1 External trip (Auxiliary) input. • Check remote wiring.
• Verify communications
programming for intentional fault.
F003 Power Loss 2 Single phase operation detected with
excessive load. • Monitor the incoming AC line for low
voltage or line power interruption.
• Check input fuses.
• Reduce load.
F004 UnderVoltage 1 DC bus voltage fell below the minimum
value. Monitor the incoming AC line for low
voltage or line power interruption.
F005 OverVoltage 1 DC bus voltage exceeded maximum
value. 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.
F006 Motor Stalled 1 Drive is unable to accelerate or
decelerate motor. • 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.
F007 Motor Overload 1 Internal electronic overload trip. • 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.
F008 Heatsink OvrTmp 1 Heatsink/Power Module temperature
exceeds a predefined value. • Check for blocked or dirty heat sink
fins. Verify that ambient
temperature has not exceeded the
rated ambient temperature.
• Check fan.
F009 CC OvrTmp 1 Control module temperature exceeds a
predefined value. • Check product ambient
temperature.
• Check for airflow obstruction.
• Check for dirt or debris.
• Check fan.
F012 HW OverCurrent 2 The drive output current has exceeded
the hardware current limit. Check programming. Check for excess
load, improper
A530 [Boost Select]
setting, DC brake volts set too high or
other causes of excess current.
F013 Ground Fault 1
(3)
A current path to earth ground has been
detected at one or more of the drive
output terminals. Check the motor and external wiring to
the drive output terminals for a
grounded condition.
