Description
Displays the value of analog input AI1 in mA or V (depending
on whether the input is set to current or voltage by a hardware
setting).
This parameter is read-only.
Value of analog input AI1.
Displays the value of analog input AI1 after scaling. See
parameters 12.19 AI1 scaled at AI1 min
at AI1 max.
This parameter is read-only.
Scaled value of analog input AI1.
Selects the unit for readings and settings related to analog
input AI1.
Note: This setting must match the corresponding hardware
setting on the drive control unit (see the hardware manual of
the drive). Control board reboot (either by cycling the power
or through parameter 96.08 Control board
validate any changes in the hardware settings.

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.
Filter time constant.
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.
