188 Parameters
11.43 Freq in 1 max Defines the maximum for the frequency actually arriving at
frequency input 1 (DI5 or DI6 when it is used as a frequency
input). See parameter
11.42 Freq in 1 min .
16000 Hz
0 … 16000 Hz Maximum frequency for frequency input 1 (DI5 or DI6). 1 = 1 Hz
11.44 Freq in 1 at scaled
min Defines the value that is required to correspond internally to
the minimum input frequency defined by parameter
11.42
Freq in 1 min . See diagram at parameter 11.42 Freq in 1 min .

-32768.000…
32767.000 Value corresponding to minimum of frequency input 1. 1 = 1
11.45 Freq in 1 at scaled
max Defines the value that is required to correspond internally to
the maximum input frequency defined by parameter
11.43
Freq in 1 max . See diagram at parameter 11.42 Freq in 1 min .
50.000
-32768.000…
32767.000 Value corresponding to maximum of frequency input 1. 1 = 1

12 Standard AI Configuration of standard analog inputs.
12.02 AI force selection The true readings of the analog inputs can be overridden for
e.g. 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 12.16 AI1 filter time and
12.26 AI2 filter time ) have no effect on forced AI values
(parameters 12.13 AI1 forced value and 12.23 AI2 forced
value ).
Note: Boot and power cycle reset the force selections
(parameters 12.02 and 12.03 ).

0b000...0b1111 Forced values selector for analog inputs AI1 and AI2. 1 = 1
12.03 AI supervision
function Selects how the drive reacts when an analog input signal
moves out of the minimum and/or maximum limits specified
for the input.
The supervision applies a margin of 0.5 V or 1.0 mA to the
limits. For example, if the maximum limit for the input is
7.000 V, the maximum limit supervision activates at 7.500 V.
The inputs and the limits to be observed are selected by
parameter
12.04 AI supervision selection .
No action
No action No action taken. 0
Fault Drive trips on 80A0 AI supervision . 1
Warning Drive generates an A8A0 AI supervision warning. 2
Last speed Drive generates a warning ( A8A0 AI supervision ) 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.
