8. Click the Tune tab.
9. Configure the parameters in the Tune tab as suggested in the Initial Setting
column, leaving all other tune options off for your first pass.
If necessary, reduce the Velocity Loop Proportional Gain to maintain
stability.
WARNING: Large Position Error Tolerances, such as those
calculated by the Auto Tune function in the RSLogix 5000
programming software, or when configuring a new axis with the
RSLogix 5000 software, can lead to undetected and repetitive
high-energy impacts against axis end stops if proper precautions
are not in place. These tolerances can also lead to undetected and
repetitive high-energy impacts against unexpected obstructions.
Such impacts can lead to equipment damage and/or serious injury.
To identify the safety concerns that you have with default Position
Error Tolerance or after an Auto Tune Function, go to the Rockwell
Automation Knowlegebase. Click Find Technical Support Answers
