Troubleshooting the Kinetix 6000 Drive System Chapter 7
E35
DriveUndervoltage Fault
(Precharge Fault)
Converter precharge cycle
failed.
Low AC input voltage. Check input AC voltage on all phases.
Internal malfunction. Call your sales representative.
E36
DriveOvertemp Fault
(System Overtemperature)
Converter thermal switch
tripped.
Excessive heat exists in the power circuitry.
• Reduce acceleration rates.
• Reduce duty cycle (ON/OFF) of commanded
motion.
• Increase time permitted for motion.
• Use larger IAM converter module.
• Check for clogged vents or defective fan.
• Make sure cooling is not restricted by
insufficient space around the unit.
E37
PowerPhaseLoss Fault
(Phase Loss Flt)
• One or more phases of the input AC power is missing.
• Axis was enabled when main (three-phase) power was removed.
• common-bus follower axis was enabled when DC bus power was removed.
• Check input AC voltage on all phases.
• Disable axis before removing power.
E38
SercosFault
(Sercos Ring Flt)
The Sercos ring is not active
after being active and
operational.
Cable disconnected.
Check that fiber-optic cable is present and
connected properly.
E39
DriveHardFault
(Self Sense Flt)
Self-sensing Commutation
Start-up Error
Motion required for self-sensing start-up
commutation was obstructed.
• 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 by using wiring
diagnostics.
E43
DriveEnableInput Fault
(Drive Enable Flt)
Missing Drive Enable Input
Signal
• An attempt was made to enable the axis
through software while the Drive Enable
hardware input was inactive.
• The Drive Enable input transitioned from
active to inactive 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.
E49
DriveHardFault
(Safe-off HW Flt)
Safe torque-off function
mismatch. Drive does not
allow motion.
• Loose wiring at STO connector.
• Cable/header not seated properly in STO
connector.
• Safe torque-off circuit missing +24V DC.
• Verify wire terminations, cable/header
connections, and +24V.
• Reset error and run proof test.
• If error persists, return the drive to Rockwell
Automation.
E50
SercosFault
(Sercos Same ADDR)
Duplicate node address detected on Sercos ring.
Verify that each Sercos drive is assigned a unique
node address.
E54
DriveHardFault
(Ifbk HW Fault)
Current feedback hardware fault detected. Replace the module.
E55 OverSpeedFault
The velocity error limit has
been exceeded.
Motor has exceeded velocity error limit Check the cables for noise.
E60
DriveHardFault
(Unknown Axis)
Illegal ID bits detected Replace the module.
E61
AuxFeedbackFault
(Aux Fdbk AQB)
Auxiliary Encoder State Error
T
he
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
(Aux Fdbk Loss)
The feedback wiring is open, shorted, or missing.
Check the motor feedback cable connectors/wiring
to the IAM/AM module and servo motor.
E63
AuxFeedbackNoise
(Aux Fdbk Noise)
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
(Mtr Fdbk Noise)
Noise on motor feedback
cable.
