Description
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
(page 55). Control board reboot (either by cycling the power
or through parameter 96.08 Control board
validate any changes in the hardware settings.

Filter time constant.
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.
Minimum value of AI2.
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.
Maximum value of AI2.
