Troubleshooting the Kinetix 6000 Drive System
Presence of noise on command
or motor feedback signal wires.
Recommended grounding per installation instructions have not
been followed.
•
Verify grounding.
•
Route wire away from noise sources.
•
Refer to System Design for Control of
Electrical Noise, publication GMC-RM001.
Line frequency may be present.
•
Verify grounding.
•
Route wire away from noise sources.
Variable frequency may be velocity feedback ripple or a disturbance
caused by gear teeth or ballscrew balls etc. The frequency may be a
multiple of the motor power transmission components or ballscrew
speeds resulting in velocity disturbance.
•
Decouple the motor for verification.
•
Check and improve mechanical performance
of the gearbox, ballscrew, etc.
No rotation
The motor connections are loose or open.
Check motor wiring and connections.
Foreign matter is lodged in the motor.
Remove foreign matter.
The motor load is excessive.
Verify the servo system sizing.
The bearings are worn.
Return the motor for repair.
The motor brake is engaged (if supplied).
•
Check brake wiring and function.
•
Return the motor for repair.
The motor is not connect to the load.
Check coupling.
Motor overheating
The duty cycle is excessive.
Change the command profile to reduce accel/
decel or increase time.
The rotor is partially demagnetized causing excessive motor
current.
Return the motor for repair.
Abnormal noise
Motor tuning limits are set too high.
Run Tune in RSLogix 5000 software again.
Loose parts are present in the motor.
•
Remove the loose parts.
•
Return motor for repair.
•
Replace motor.
Through bolts or coupling is loose.
Tighten bolts.
The bearings are worn.
Return motor for repair.
Mechanical resonance
Notch filter may be required (refer to Axis
Properties dialog, Output tab in RSLogix 5000
software).
Erratic operation - Motor
locks into position, runs
without control or with
reduced torque.
Motor power phases U and V, U and W, or V and W reversed.
Check and correct motor power wiring.
Sine, Cosine or Rotor leads are reversed in the feedback cable
connector.
Check and correct motor feedback wiring.
Sine, Cosine, Rotor lead sets of resolver feedback are reversed.
Check and correct motor feedback wiring.
