Chapter 6 Troubleshoot the Kinetix 7000 Drive System
E18 OverSpeedFault
Motor speed has exceeded 150% of maximum rated speed. The 100% trip
point is dictated by the lesser of the user velocity limits or the motor rated
base speed.
Check cables for noise.
Check tuning.
Check feedback device.
Verify velocity limit settings.
E19 PositionErrorFault Position error limit exceeded.
Increase the feed forward gain.
Increase following error limit or time.
Check position loop tuning.
Verify sizing of system.
Verify mechanical integrity of system within
specification limits.
E20 MotFeedbackFault Motor encoder state error.
The motor 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.
Check feedback device and wiring.
E21 AuxFeedbackFault Communication was not established with an intelligent encoder. Verify auxiliary encoder wiring.
E23 DriveOvertempFault
IPM thermal protection
fault The internal filter protecting the drive from
overheating has tripped.
Reduce acceleration rates.
Reduce duty cycle (ON/OFF) of commanded motion.
Increase time permitted for motion.
Use larger Kinetix 7000 drive and motor.
Check tuning.
E30 MotFeedbackFault Communication was not established with an intelligent encoder.
Verify motor selection.
Verify the motor supports automatic identification.
Verify motor encoder wiring.
E34 GroundShortFault
Excessive ground current
detected in the converter.
Wiring error.
Check motor power wiring.
Check input 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 clears, then a
wiring error or motor internal problem exists. If fault
remains, call your Rockwell Automation sales
representative.
Remove ground from control power input.
Wire control power to use main power as shown in
Appendix B.
Add isolation transformer for control power.
E35 DriveUndervoltageFault
Converter precharge cycle
failed.
Low AC input voltage. Check input AC voltage on all phases.
Internal malfunction. Call your Rockwell Automation sales representative.
E37 PowerPhaseLossFault One or more phases of the ac input power is missing.
Check input ac voltage and fusing on all phases and
DC bus.
Disable axis before removing power.
