Hi everyone,
I have a problem which occurs time after time (but not always): I would like to modify a named position via the FlexPendant, using the Program Editor view. I run the program and stop it at the desired target, so the motion pointer is set. Then I jog away, and select the position name and click on “Modify position”. After the confirmation a window appears, that “Modify Position Error - Unable to modify the position”. I didn’t find anything in the manuals nor in Google search about what can cause this problem.
Do you have any idea or suggestion?
Thank you very much,
Virag

Check so that you have proper tool AND proper work object selected in the jogging window.

Thanks, but they do correspond. If we choose wrong workobject or tool, then we get a message about it – but in our case, no explanation, only “Modify Position Error - Unable to modify the position”.

Check with "Debug-\>“View value” ïf the position has a value. If not this message will appear.
If the position has no value change it’s declaration.
This is wrong
_VAR robtarget pUnload;_
This is correct
_VAR robtarget pUnload:=[[-657.32,-485.01,92.14],[4.06594E-05,-0.707061,0.707159,6.52999E-05],[-1,0,0,1],[9E+09,9E+09,9E+09,9E+09,9E+09,9E+09]];_
Do a PP to routine to make sure the position has its value and try again.
