172 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.

Note:
The number of active bits in this parameter depends on
the number of inputs on the extension module.

For the available selections, see parameter
(Visible when
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.

.
No action
Tuning action completed or no action has been requested.
The parameter automatically reverts to this value after any
tuning action.
0
AI1 min tune
The measured value of AI1 is set as the minimum value of AI1
into parameter
.
1
AI1 max tune
The measured value of AI1 is set as the maximum value of
AI1 into parameter
.
2
AI2 min tune
The measured value of AI2 is set as the minimum value of AI2
into parameter
.
