Description
Drive generates a warning
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.
Drive generates a warning
the speed to the speed defined by parameter
ref safe (or 28.41 Frequency ref safe
reference is being used).
WARNING! Make sure that it is safe to continue
operation in case of a communication break.
(Visible when 14.01 Module 1 type
Specifies the analog input limits to be supervised. See
parameter 14.19 AI supervision
Note: The number of active bits in this parameter depends
on the number of inputs on the extension module.
Description
1 = Minimum limit supervision of AI1 active.
1 = Maximum limit supervision of AI1 active.
1 = Minimum limit supervision of AI2 active.
1 = Maximum limit supervision of AI2 active.
1 = Minimum limit supervision of AI3 active (FIO-11 only).
1 = Maximum limit supervision of AI3 active (FIO-11 only).
Activation of analog input supervision.

DIO3 when parameter 14.19 DIO3 function
For the available selections, see parameter
output source.
(Visible when 14.01 Module 1 type
Triggers the analog input tuning function, which enables the
use of actual measurements as the minimum and maximum
input values instead of potentially inaccurate estimates.
Apply the minimum or maximum signal to the input and
select the appropriate tuning function.
See also the drawing at parameter
min.
Tuning action completed or no action has been requested.
The parameter automatically reverts to this value after any
tuning action.
The measured value of AI1 is set as the minimum value of
AI1 into parameter 14.33 AI1
The measured value of AI1 is set as the maximum value of
AI1 into parameter 14.34 AI1
The measured value of AI2 is set as the minimum value of
AI2 into parameter 14.48 AI2
