Description
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.
Note: AI filter times (parameters
12.26 AI2 filter time) have no effect on forced AI values
(parameters 12.13 AI1 forced value
value).
Note: Boot and power cycle reset the force selections
(parameters 12.02 and 12.03).
Forced values selector for analog inputs AI1 and AI2.
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 12.04 AI supervision
No action taken.
Drive trips on 80A0 AI supervision.
Drive generates an A8A0 AI supervision
Drive generates a warning
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
speed to the speed defined by parameter
safe (or 28.41 Frequency ref safe
is being used).
WARNING! Make sure that it is safe to continue
operation in case of a communication break.
Specifies the analog input limits to be supervised. See
parameter 12.03 AI supervision
