Parameters 87
12.25 AI2 unit selection Selects the unit for readings and settings related to analog
input AI2.
Note:
In firmware ASCL2 and ASCL4), this setting must
match the corresponding hardware setting on the drive
control unit. chapter Electrical installation, section Switches in
the Hardware manual of the drive and the default control
connections for the macro in use in chapter Control macros
(page 55). Control board reboot (either by cycling the power
or through parameter 96.08 Control board boot) is required to
validate any changes in the hardware settings.

mA Milliamperes. 10
12.26 AI2 filter time Defines the filter time constant for analog input AI2. See
parameter 12.16 AI1 filter time.
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
0.000…22.000 Minimum value of AI2. 1000 = 1 unit
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
0.000…22.000 mA Maximum value of AI2. 1000 = 1 unit
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.)

12.30 AI2 scaled at AI2
max
Defines the real value that corresponds to the minimum
analog input AI2 value defined by parameter 12.28 AI2 max.
See the drawing at parameter of 12.29 AI2 scaled at AI2 min.
