124 Parameters
12
Configuration of standard analog inputs.
The true readings of the analog inputs can be overridden for
eg. testing purposes. A forced value parameter is provided for
each analog input, and its value is applied whenever the
corresponding bit in this parameter is 1.

Forced values selector for analog inputs AI1 and AI2.
1 = 1
Selects how the drive reacts when an analog input signal
moves out of the minimum and/or maximum limits specified
for the input.
The inputs and the limits to be observed are selected by
parameter
No action
No action taken.
0
Fault
Drive trips on
.
1
Warning
Drive generates an
warning.
2
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
when frequency reference
is being used).
WARNING!
Make sure that it is safe to continue
operation in case of a communication break.
