5.5 SERVO DRIVE FAULT TABLE
Fault
Number
Fault Name Fault Description Possible Cause(s)
Suggested Action
1 Non-Volatile Memory
Endurance Exceeded A section of non-volatile
memory is used to assist in
tracking absolute position
when the drive is connected
to a motor with absolute
feedback. This fault occurs
when the total number of
memory writes to this area
exceeds the maximum
value allowed.
Range of motion and number
of home position definitions
during the product life exceeds
the maximum allowed.
This is an unrecoverable fault,
the drive must be sent back to
the factory
2 Position Change
Exceeds Position
Rollover This fault is generated if the
change in position
command or position
feedback exceeds half the
machine cycle size during a
position loop update. This
effectively limits the velocity
to half the machine cycle
size per millisecond.
The velocity command or
feedback exceeds half the
machine cycle length per
millisecond. Increase machine cycle size
or reduce velocity profile.
Note: This error only applies to
firmware versions prior to
1.10.
3 Absolute Feedback
Range Exceeded This fault is generated if the
motor position exceeds +/-
2047 revolutions from the
home position, but can only
be generated in firmware
versions 1.00 and 1.02.
The motor position exceeds
+/- 2047 revolutions from the
home position. Decrease application range of
motion.
Upgrade firmware.
4 Motor Overtemperature
ON indicates the motor
thermostat has tripped.
Motor thermostat trips due to
high motor ambient
temperature and/or excessive
current.
Motor wiring error
Incorrect motor selection
Operate within (not above) the
continuous torque rating for
the ambient temperature
(40ºC maximum).
Lower ambient temperature,
increase motor cooling.
Check motor wiring.
Verify the proper motor has
been selected.
5 IPM Fault
ON indicates that a fault
was detected in the
Integrated Power Module
which resides in the
Ultra3000 drive.
Motor cables shorted.
Motor winding shorted
internally.
Ultra3000 temperature too
high.
Operation above continuous
power rating. Disconnect motor power
cables from the drive. If faults
stop, then either replace cable
or try to find the short.
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.
Check for clogged vents or
defective fan.
Ensure cooling is not
restricted by insufficient space
around the unit.
Verify ambient temperature is
not too high. Operate within
