Configuring the Ultra3000 Drive Chapter 3
32: Excessive
Interpolated
Feedback
Frequency ON indicates Sine/
Cosine frequency of
encoder exceeds
maximum value.
Note: This fault can only
be generated when the
encoder output is
synthesized by the
Ultra3000. Encoder output
frequency exceeds the
maximum value. • Reduce motor speed.
• Use encoder with
lower resolution
(before interpolation).
33: Absolute
Position Exceeds
Position Rollover ON indicates motion is
commanded to a position
outside the position
rollover range. The
position rollover range is
[0. machine cycle size -
1].
Note: This fault can only
be generated when the
machine cycle position
rollover is enabled. An absolute index is
initiated that specifies a
position outside the
position rollover range.
A homing cycle is
initiated with the home
position outside the
position rollover range.
A define home is
initiated with the home
position outside the
position rollover range.
A preset position is
initiated that specifies a
position outside the
position rollover range.
The home position
parameter is changed to
a value outside the
position rollover range,
the system has absolute
feedback and the drive is
reset or power cycled. Set motion command to
a position within the
position rollover range.
34: Ground Short
Circuit ON indicates the motor
ground is shorted. Wiring fault
Motor internal ground
short
Internal malfunction Disconnect motor power
cable from drive and
enable drive with current
limit set to 0.
• If fault remains, call
your A-B
representative.
• If fault clears, a wiring
fault or an fault
internal to the motor
exists.
35: Soft-Starting
Fault ON indicates a soft fault
at startup. Low AC input voltage Check AC input voltage
on all phases.
Internal malfunction Call your A-B
representative.
