Problem
Problem Problem
Auxiliary input interlock is open.
Excessive DC Bus voltage ripple.
DC bus voltage fell below the
minimum value.
DC bus voltage exceeded the
maximum value.
The drive is unable to accelerate
the motor.
Internal electronic overload trip.
Heatsink temperature exceeds a
predefined value.
The drive output current has
exceeded the hardware current
limit.
A current path to the earth ground
has been detected at one or more
of the drive output terminals.
The drive unsuccessfully
attempted to reset a fault
and resume running for the
programmed number of auto
restart tries (A451).
Events and Logs
Solution
Solution Solution
• Check the remote wiring.
• Verify communications programming
for intentional fault.
• Monitor the incoming line for phase
loss or line imbalance.
• Check the input line fuse.
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
install a dynamic brake option.
Increase P109 and/or A402 (accel time)
or reduce the load so the drive output
current does not exceed the current set
by the Current Limit parameter (A441).
• An excessive motor load exists.
Reduce the load so the drive output
current does not exceed the current
set by the Motor OL Current parameter
(P103).
• Verify the Boost Select setting (A453).
• Check for blocked or dirty heat
sink fins. Verify that the ambient
temperature has not exceeded 40° C
(104° F) for IP 30/NEMA 1/UL Type
1 installations or 50° C (122° F) for
IP10/Open type installations.
• Check the fan.
Check the programming. Check for
excess load, an improper Boost Select
setting (A453), 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.
Correct the cause of the fault and
manually clear.
