DESCRIPTION
Input is open.
DC bus voltage remained below 85% of
nominal for longer than Power Loss Time
(185).
Enable/disable with Fault Config 1 (238).
DC bus voltage fell below the minimum
value of 407V DC at 400/480V input
Enable/disable with Fault Config 1(233).
DC bus voltage exceeded maximum value. Monitor the AC line for high line voltage or
Internal electronic overload trip.
Enable/disable with Fault Config 1 (238).
Base temperature exceeded limit.
Output transistors have exceeded their
maximum operating temperature.
The drive output current has exceeded the
hardware current limit.
A current path to earth ground in excess of
7% of drive rated amps has been detected
at one or more of the drive output
terminals.
The drive is not following a commanded
deceleration because it is attempting to
limit bus voltage.
Functions such as slip compensation or
bus regulation have attempted to add an
output frequency adjustment greater than
that programmed in Overspeed Limit (83).
An analog input is configured to fault on
signal loss. A signal loss has occurred.
Configure with Anlg In 1, 2 Loss (324, 327).
Drive unsuccessfully attempted to reset a
fault and resume running for the pro-
grammed number of Auto Rstrt Tries (174).
Enable/disable with Fault Config 1 (238).
The magnitude of motor current feedback
was less than 5% of the configured Motor
Nameplate Amps for the time configured in
the Motor Imbalance Time. Detection of
this fault is disabled when the Motor Imbal-
ance Time is set to the maximum value of
10.0 seconds.
The drive output current has exceeded the
software current.
Phase current displayed in Imbalance Dis-
play (221) > percentage set in Imbalance
Limit (49) for time set in Imbalance Time
(50).
ACTION
Check remote wiring.
Monitor the incoming AC line for low voltage or
line power interruption.
Monitor the incoming AC line for low voltage or
power interruption.
transient conditions. Bus overvoltage can also
be caused by motor regeneration. Extend the
decel time or install dynamic brake option.
An excessive motor load exists. Reduce load
so drive output current does not exceed the
current set by Motor NP FLA (42).
Check for proper temperature and flow rate of
coolant.
Check for proper temperature and flow rate of
coolant.
Check programming. Check for excess load,
improper DC boost 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.
a. Verify input voltage is within drive specified
limits.
b. Verify system ground impedance follows
proper grounding techniques.
c. Disable bus regulation and/or add dynamic
brake resistor and/or extend deceleration
time.
Remove excessive load or overhauling condi-
tions or increase Overspeed Limit (83).
a. Check parameters.
b. Check for broken/loose connections at
inputs.
Correct the cause of the fault and manually
clear.
Verify connection of current feedback device
and motor terminals. If fault repeats replace
current feedback devices and/or power supply.
Check for excess load, improper DC boost set-
ting. DC brake volts set too high.
Clear fault.
