APPENDIXES
33 Iavg Fault The average current output of the ULTRA Plus or IQ
exceeded safe levels for the motor or PDM module.
Check for correct connection of the motor encoder to the
ULTRA Plus or IQ or of the motor leads to the PDM.
Another possible cause is motor stall or end of travel
condition, excessive duty cycle, or no DC bus (drive)
voltage. For PDMs only, this fault can also occur if there
is power supplied to the L1 and L2 AC AUX inputs, but
not to the L1 and L2 AC main inputs (this provides logic
voltage, but no DC bus voltage).
34 Excessive FE The following error has exceeded the Following Error
Limit for a time greater than the Following Error Time.
Possible causes are loss of encoder feedback, low gain
settings, low current limit settings, a commanded veloc-
ity or acceleration that exceeds system capabilities, or
entries for Following Error Limit and/or Following
Error Time that are beyond system capabilities.
35 Excessive Speed Commanded velocity of a move exceeded the Over-
speed value set in the Parameter menu, Velocity/Accel
dialog box
36 Cam Profile Overflow The target follower position in a cam profile could not
be calculated.
37 Pos Track Overflow The target follower position with tracking mode active
could not be calculated.
39 Drive Not Ready IQ-550 only. The Ready to Run signal from the drive
went false, indicating a fault in the drive.
40 Motor Overtemperature The temperature sensor in the motor windings indicated
that the motor temperature has exceeded the rating.
Check for mechanical binding, undersized motor, or
duty cycle too high.
41 Heat Sink Overtemperature This fault typically indicates that the amplifier is trying
to supply currents above its rating to the motor. Check
for mechanical binding, excessive duty cycle, or faulty
motor wiring.
ULTRA Plus or IQ-2000: The ULTRA Plus or IQ-2000
power module has detected excessive internal tempera-
ture or excessive current to the motor. On earlier power
modules, this fault indicates the heat sink temperature
has exceeded the rated temperature.
ULTRA Plus or IQ-5000: The heat sink temperature has
exceeded the rating.
42 Logic Supply Fault Power supplies for the amplifier circuitry were below
the nominal output voltage. This indicates a problem in
the ULTRA Plus or IQ internal power supply.
43 Peak Overcurrent The PDM current sensors detected a short circuit in the
motor leads. Check motor power cables for shorts.
