Motor jumps when first enabled Motor wiring error. Check motor wiring.
Incorrect motor chosen. Verify the proper motor is selected.
Digital I/O not working correctly I/O power supply disconnected or
incorrect I/O type Verify:
• I/O connections
• I/O power source
• I/O type (sinking/sourcing).
01 - 03 Reserved Call your local Allen-Bradley
representative.
04 Motor Overtemperature Motor thermostat trips due to:
• High motor ambient temperature
and/or
• Excessive current
• Operate within (not above) the
continuous torque rating for the
ambient temperature (40°C
maximum).
• Lower ambient temperature,
increase motor cooling.
Motor wiring error. Check motor wiring.
Incorrect motor selection. Verify the proper motor has been
selected.
05 IPM Fault Motor cables shorted. Verify continuity of motor power cable
and connector.
Motor winding shorted internally. Disconnect motor power cables from
the motor. If the motor is difficult to
turn by hand, it may need to be
replaced.
Ultra5000 temperature too high.
• Check for clogged vents or
defective fan.
• Ensure cooling is not restricted by
insufficient space around the unit.
Operation above continuous power
rating.
• Verify ambient temperature is not
too high.
• Operate within the continuous
power rating.
• Reduce acceleration rates.
Ultra5000 has a bad IPM output, short
circuit, or overcurrent. Remove all power and motor
connections, and preform a continuity
check from the DC bus to the U, V, and
W motor outputs. If a continuity exists,
check for wire fibers between
terminals, or send drive in for repair.
06 - 08 Reserved Call your local Allen-Bradley
representative.
09 Bus Undervoltage Low AC line/AC power input.
• Verify voltage level of the incoming
AC power.
• Check AC power source for glitches
or line drop.
• Install an uninterruptible power
supply (UPS) on your AC input.
