WARNING
Large Position Error Tolerances, such as those calculated
by the Auto Tune function in RSLogix 5000 programming
software, or when configuring a new axis with 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
