154 Minimizing the Effects of Feedback Signal Loss
Position Error Limit
Adjustment Example with
RSLogix 5000 Software This example uses RSLogix 5000 software, a ControlLogix controller
(catalog number 1756-L63), and an Ultra3000i indexing drive (catalog
number 2098-DSD-030X) with a 230V MP-Series motor (catalog
number MPL-A330P-S) and appropriate power and communication
cables to illustrate position error limit setting optimization. A simple
motion application is used in this example to perform a repeating
clockwise-counterclockwise incremental axis move.
In this example, you will observe the default position error limit
setting in RSLogix 5000 software and, with the motion application
running, observe the actual application position error excursion limit
values. This is done by using the trending feature of the RSLogix 5000
software. Based on these excursion limit values, you can adjust the
default position error limit settings to closely match the needs of the
application under normal operating conditions. Finally, with the new
position error limit setting in place, you can test the system to make
sure that it is still functional and that no nuisance faults occur.
