160 Parameters
Last speed
Drive generates a 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.
3
Speed ref safe
Drive generates a warning (
) and sets the
speed to the speed defined by parameter
(or
is being used).
WARNING!
Make sure that it is safe to continue
operation in case of a communication break.

0000b
0000b…1111b
Activation of analog input supervision.
1 = 1
Activates analog input supervision separately for each control
location (see section
Local control vs. external control
on
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.

Analog input supervision selection.
1 = 1
Displays 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).
This parameter is read-only.
