168 Parameters
12.17 AI1 min Defines the minimum site value for analog input AI1.
Set the value actually sent to the drive when the analog signal
from plant is wound to its minimum setting.
See also parameter 12.19 AI1 scaled at AI1 min.
4.000 mA or
0.000 V
0.000…20.000 mA
or 0.000…10.000 V
Minimum value of AI1. 1000 = 1 unit
12.18 AI1 max Defines the maximum site value for analog input AI1.
Set the value actually sent to the drive when the analog signal
from plant is wound to its maximum setting.
See also parameter 12.19 AI1 scaled at AI1 min.
20.000 mA or
10.000 V
0.000…20.000 mA
or 0.000…10.000 V
Maximum value of AI1. 1000 = 1 unit
12.19 AI1 scaled at AI1
min
Defines the real internal value that corresponds to the
minimum analog input AI1 value defined by parameter 12.17
AI1 min. (Changing the polarity settings of 12.19 and 12.20
can effectively invert the analog input.)
0.000
-32768.000…
32767.000
Real value corresponding to minimum AI1 value. 1 = 1
12.20 AI1 scaled at AI1
max
Defines the real internal value that corresponds to the
maximum analog input AI1 value defined by parameter 12.18
AI1 max. See the drawing at parameter 12.19 AI1 scaled at
AI1 min.
50.000
-32768.000…
32767.000
Real value corresponding to maximum AI1 value. 1 = 1
12.21 AI2 actual value Displays the value of analog input AI2 in mA or V (depending
on whether the input is set to current or voltage by a hardware
setting).
This parameter is read-only.
-
0.000…20.000 mA
or 0.000…10.000 V
Value of analog input AI2. 1000 = 1 unit
12.22 AI2 scaled value Displays the value of analog input AI2 after scaling. See
parameters 12.29 AI2 scaled at AI2 min and 12.101 AI1
percent value.
This parameter is read-only.
