Chapter 4 Configuring the Ultra5000 Drive
05: IPM Fault ON indicates that a fault
was detected in the
Integrated Power
Module which resides in
the Ultra5000 drive. Motor cables shorted Disconnect motor power
cables from the drive. If
faults stop, then either
replace cable or try to
find the short.
Motor winding shorted
internally. Verify by disconnecting
motor from drive and
then try to turn by hand.
If difficult to turn by
hand, the motor needs to
be repaired or replaced.
Ultra5000 temperature
too high.
• Check for clogged
vents or defective fan.
• Ensure cooling is not
restricted by
insufficient space
around the unit.
Operation above
continuous power rating. • Verify ambient
temperature is not too
high. Operate within
the continuous power
rating.
• Increase Motion Time
or dwell periods.
• Reduce acceleration
rates.
Ultra5000 has a bad IPM
output, short circuit, or
overcurrent,
Check continuity from
the DC bus to U, V, and
W outputs. If continuity
exists, check for
conductive materials
between terminals.
09: Bus
Undervoltage ON indicates the DC Bus
is below normal
operating voltage. Low AC line/AC power
input. 100 VAC minimum
for safe Ultra5000
operation.
• Verify voltage level of
the DC Bus. The Bus
should be 1.414*VAC
level.
• Check AC power
source for glitches or
line drop.
• Install an
uninterruptible power
supply (UPS) on your
VAC input.
ON indicates the DC Bus
is below normal
operating voltage. Excessive regeneration
of power. When the drive
is driven by an external
mechanical power
source, it may
regenerate too much
peak energy through the
drive's power supply. The
system faults to save
itself from an overload. • Change the
deceleration or motion
profile.
• Use a larger system
(motor and Ultra5000).
• Use an Active Shunt.
Excessive AC input
voltage. Verify input is below 264
VAC.
