Drive generates a warning (A8A0 AI Supervised Warning)
and sets the speed to the speed defined by parameter
22.41 Speed ref safe (or 28.41 Frequency ref safe when
frequency reference is being used).
WARNING!
Make sure that it is safe to continue operation in
case of a communication break.

- / uint16Activates analog input supervision separately for each
control location (see section Local control vs. external
control (page 23)).
The parameter is primarily intended for analog input
supervision when the input is connected to the application
program and not selected as a control source by drive
parameters.

- / real32Displays the value of analog input AI1 in mA or V
(depending on whether the input is set to current or voltage
by a hardware setting).
