Parameters 119
12.26 AI2 filter time
Defines the filter time constant for analog input AI2.
See parameter
12.16 AI1 filter time
.
Note: The signal is also filtered due to the signal
interface hardware (approximately 0.25 ms time
constant). This cannot be changed by any parameter.
0.100 s
0.000…30.000 s Filter time constant. 1000 = 1 s
12.27 AI2 min
Defines the minimum site value for analog input AI2.
Set the value actually sent to the drive when the
analog signal from plant is wound to its minimum
setting.
4.000 mA or
0.000 V
0.000…22.000 mA
or 0.000…11.000 V Minimum value of AI2. 1000 = 1 mA
or V
12.28 AI2 max
Defines the maximum site value for analog input AI2.
Set the value actually sent to the drive when the
analog signal from plant is wound to its maximum
setting.
20.000 mA
or 10.000 V
0.000…22.000 mA
or 0.000…11.000 V Maximum value of AI2. 1000 = 1 mA
or V
12.29 AI2 scaled at AI2 min
Defines the real value that corresponds to the
minimum analog input AI2 value defined by
parameter
12.27 AI2 min
. (Changing the polarity
settings of
12.29
and
12.101
can effectively invert the
analog input.)
0.000
-32768.000…
32767.000
Real value corresponding to minimum AI2 value. 1 = 1
12.30 AI2 scaled at AI2 max Defines the real value that corresponds to the
maximum analog input AI2 value defined by
parameter 12.28 AI2 max . See the drawing at
parameter of 12.29 AI2 scaled at AI2 min
50.000
-32768.000…
32767.000
Real value corresponding to maximum AI2 value. 1 = 1
12.101 AI1 percent value Value of analog input AI1 in percent of AI1 scaling
( 12.18 AI1 max - 12.17 AI1 min ).
-
0.00… 100.00 AI1 value 100 = 1%
12.102 AI2 percent value Value of analog input AI2 in percent of AI1 scaling
( 12.28 AI2 max - 12.27 AI2 min ).
