3 Drive generates a warning ( A8A0 AI Supervised
Warning ) and freezes the speed (or frequency) to the
level the drive was operating at. The speed/frequency
is determined on the basis of actual speed using 850
ms low-pass filtering.
WARNING!
Make sure that it is safe to continue operation
in case of a communication break.
Last speed
4 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.

- / uint16 Activates analog input supervision separately for each
control location (see section
Local control vs. external
control (page 39) ).
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.
