LIMFNCi-aT changes the functionality of the Limits to Homing inputs. However, only Home inputs can be changed to this. Therefore, a user cannot change a limit to function as a Home input.
The -aT functionality was add to the LIMFNC command so that a user could change a Home input to a programmable input with other functionality, then would be able to change it back.
The End-of-Travel Limits are also limited to either the -A function or the respective EOT limit function.
