Troubleshoot the Kinetix 7000 Drive System Chapter 6
E38 SERCOSFault
The SERCOS ring is not active
after being active and
operational.
Cable disconnected.
Check that fiber-optic cable is present and properly
connected.
E39 DriveHardFault
Self-sensing Commutation
Startup Error. Obstruction prevents motion required for self-
sensing startup commutation.
Verify that there are no impediments to motion at
startup, such as hard limits.
Increase self-sensing current if high friction or load
conditions exist.
Check motor or encoder wiring using wiring
diagnostics.
E43 DriveEnableInputFault
Missing Drive Enable input
signal.
Attempted to enable the axis through
software while the Drive Enable hardware
input was inactive.
The Drive Enable input transition from active
to inactive occurred while the axis was
enabled.
Disable the Drive Enable Input fault.
Verify that Drive Enable hardware input is active
whenever the drive is enabled through software.
Verify wiring and shielding.
If error persists, return the drive to Rockwell
Automation.
E49 DriveHardFault
Safe-off function mismatch.
Drive will not permit
motion.
Loose wiring at SO connector.
Cable/header not seated properly in SO
connector.
Safe-off circuit missing +24V DC.
Verify wire terminations, cable/header connections,
and +24V DC.
Reset error and run proof test.
If error persists, return the drive to Rockwell
Automation.
Refer to the Kinetix Safe-off Feature Safety Reference Manual, GMC-RM002 , for additional troubleshooting information and proof test
procedures.
E50 SERCOSFault Duplicate node address detected on SERCOS ring.
Verify that each SERCOS drive is assigned a unique
node address.
E54 DriveHardFault
Excessive Current Feedback
Offset.
Defective current feedback sensing.
If error persists, return the drive to Rockwell
Automation.
E61 AuxFeedbackFault
Auxiliary Encoder State
Error. The auxiliary encoder encountered an illegal
transition.
Use shielded cables with twisted pair wires.
Route the feedback away from potential noise
sources.
Check the system grounds.
Replace the motor/encoder.
E62 AuxFeedbackFault The feedback wiring is open, shorted, or missing.
Check the motor feedback cable connectors/wiring
to the drive and motor.
E63 AuxFeedbackNoise
Noise on auxiliary feedback
cable.
Recommended grounding, per installation
instructions, has not been followed.
• Verify grounding.
• Route feedback cable away from noise sources.
• Refer to System Design for Control of Electrical
Noise Reference Manual, publication GMC-
RM001 .
E64 MotorFeedbackNoise
Noise on motor feedback
cable.
E65
No Fault Message
(condition indicated by on-screen
message)
Hookup procedure failed. Motor or feedback device malfunction.
Check motor power/feedback wiring.
Refer to displayed message for resolution.
E66
No Fault Message
(condition indicated by on-screen
message)
Autotune procedure failed. Motor or feedback device malfunction.
Check motor power/feedback wiring.
Refer to displayed message for resolution.
Perform Hookup in RSLogix 5000 software.
Consult RSLogix 5000 help message.
E67 DriveHardFault Operating system failed.
Software initialization fault detected due to
hardware failure.
Cycle power.
If fault persists, replace module.
E68 DriveHardFault DPI communication failed. The DPI device or cable is faulty. Check DPI connections.
