Troubleshooting the Kinetix 6000 Drive System
Possible Resolution
Check input AC voltage on all phases.
Call your sales representative.
• 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.
• Check input AC voltage on all phases.
• Disable axis before removing power.
Check that fiber-optic cable is present and
connected properly.
• 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.
• Disable the Drive Enable Input fault.
• Verify that Drive Enable hardware input is
active whenever the drive is enabled through
software.
• Verify wire terminations, cable/header
connections, and +24V.
• Reset error and run proof test.
• If error persists, return the drive to Rockwell
Automation.
Verify that each Sercos drive is assigned a unique
node address.
Replace the module.
Check the cables for noise.
Replace the module.
• Use shielded cables with twisted pair wires.
• Route the feedback away from potential noise
sources.
• Check the system grounds.
• Replace the motor/encoder.
Check the motor feedback cable connectors/wiring
to the IAM/AM module and servo motor.
• Verify grounding.
• Route feedback cable away from noise sources.
• Refer to System Design for Control of Electrical
Noise Reference Manual, publication
GMC-RM001.
