PTO Move function - absolute move to current position

[Maninashed]

Hi All,

I'm currently building a machine control application involving two axes of stepper motor control using a V430.

Does anybody know if there are any safeguards which should perhaps to be written into the user's code to guard against an absolute PTO move attempting to move to a position which is identical to the current position? That is, current position and destination position are identical so no movement is required. Does the PTO move function handle this robustly in all cases or is it safer to look for the destination=current case beforehand and then to avoid executing the PTO move instruction?

Thanks in advance.
