Why does the auto / manual functionality in menu 5 not work when have unit in PI control?

The auto / manual in menu 5 is non-compatible with PI control and to operate with auto / manual functionality have to set this up through the PI parameter for auto / manual.

When the PID regulator is configured and a logic input is configured for Auto / Manual, AI3 is the speed input in manual mode. Thus would require addition of option card to obtain AI3.
The PID regulator function is active in Auto mode. When the logic input is open, (set to state 0), Auto mode is anctive and the PID regulator is active.
Manual mode is active when the logic input is closed, (set to state 1).
In manual mode AI3 is enabled and the drive controller responds proportionally to the speed reference at AI3.
