Chapter 3 Configuring the Ultra3000 Drive
The Faults window displays the status of these faults:
Status Description Possible Cause(s) Suggested Action
Note: The value of status that are ‘ON’ = 1. The value of status that are OFF = 0.
01: 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.
Note: This fault can only
be generated for systems
with absolute feedback. Range of motion and
number of home position
definitions during the
product life exceeds the
maximum value. This is an unrecoverable
fault, the drive must be
sent back to the factory.
02: Position
Change 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.
Note: This fault can only
be generated when the
machine cycle position
rollover is enabled 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.
03: Absolute
Feedback 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.
Note: This fault can only
be generated when the
system includes absolute
feedback. The motor position
exceeds -2047…2047
revolutions from the
home position • Decrease application
range of motion.
• Upgrade firmware.
04: Motor
Overtemp ON indicates the motor
thermostat has tripped. Motor thermostat trips
due to high motor
ambient temperature,
excessive current, or
both a high temperature
and excessive current. • Operate within (not
above) the continuous
torque rating for the
ambient temperature
(40ºC maximum).
• Lower ambient
temperature, increase
motor cooling.
Motor wiring fault Check motor wiring.
Incorrect motor selection Verify the proper motor
has been selected.
