Troubleshoot the Kinetix 7000 Drive System Chapter 6
E05 DriveOvercurrent Fault
Inverter Overcurrent (IOC)
indicates a major power
related fault condition.
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.
Drive temperature too high.
Check for clogged vents or defective fan.
Verify cooling is not restricted by insufficient space
around the unit.
Operation above continuous power rating
and/or product environmental ratings.
Verify ambient temperature is not too high.
Operate within the continuous power rating.
Reduce acceleration rates.
Kinetix 7000 drive has a short-circuit,
overcurrent, or failed component.
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.
E06 HardOvertravelFault
Axis moved beyond the
physical travel limits in the
positive/negative direction.
Dedicated overtravel input is inactive.
Check wiring.
Verify motion profile.
Verify axis configuration in RSLogix 5000 software.
E07 MotFeedbackFault The feedback wiring is open, shorted, or missing.
Check motor encoder and wiring.
Run Hookup test in RSLogix 5000 software.
E09 BusUndervoltageFault
With three-phase power
present, the DC bus voltage
is below precharge limits.
Bus voltage for 460V system is below 275V
DC.
Verify voltage level of the incoming AC power.
Verify integrity and consistency of AC power source.
Install an uninterruptible power supply (UPS) on
your AC input.
DC bus voltage fell below
the undervoltage limit
while an axis was enabled.
Bus voltage is at least 180V DC below the
precharge level of 323… 525V DC.
Verify bus supply is OK.
Disable axis before removing input power.
One of more phases of AC input power failed. Check AC input power on all phases.
E10 DriveOvervoltageFault
The DC bus voltage is above
limits.
Excessive regeneration of power.
When the motor is driven by an external
mechanical power source, it may regenerate
too much peak energy through the drive’s
power supply. The system faults to save itself
from an overload.
Change the deceleration or motion profile.
Use a larger system (motor and drive).
Install shunt module.
Install larger active shunt module or regenerative
converter module.
Bus voltage for 460V system is over 800V DC.
Verify line input integrity and that it is within
specification.
E11 MotFeedbackFault
State of Hall feedback inputs
is incorrect.
Improper connection.
Verify the Hall wiring at the MF connector on the
drive.
Verify 5V power supply to the encoder.
Check feedback device.
E16 SoftOvertravelFault
Axis moved beyond the software axis position in either the positive or
negative direction.
Verify motion profile.
Verify overtravel settings are appropriate.
