Configuring the Ultra5000 Drive Chapter 4
26: User Velocity ON indicates the User
Velocity Fault level,
above, has been
exceeded. User-specified velocity
level exceeded. • Increase User Velocity
Fault Level and Time
to a less restrictive
setting.
29: Excess
Output Frequency ON indicates the motor
encoder output
frequency exceeds the
maximum value.
Note: This fault can be
generated only when the
encoder output is
synthesized by the
Ultra5000. Encoder output
frequency exceeds the
maximum value. • Increase the encoder
output Limit
parameter.
• Decrease the encoder
interpolation
parameter.
• Increase the encoder
output divider
parameter.
• Reduce motor speed.
Fault Count Displays the number of
fault encountered. — —
34: Ground Short
Circuit ON indicates the motor
ground is shorted Wiring error Check motor power
wiring.
Motor internal ground
short Replace motor.
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
error or an error 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
36: Power
Module
Overtemperature ON indicates an
overtemperature
condition in the power
module. Excessive heat in power
circuitry. • Reduce acceleration
rates.
• Reduce duty cycle
(ON/OFF) of
commanded motion.
• Increase time
permitted for motion.
• Use larger Ultra5000
and motor.
37: AC Input
Phase Loss ON indicates incorrect
power phasing. Loss of one or more
phases of power. Check AC input voltage
on all phases.
