- / real32Displays 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.

- / real32Displays the value of analog input AI1 after scaling. See
parameters 12.19 AI1 scaled at AI1 min and 12.20 AI1
scaled at AI1 max.
This parameter is read-only.

V / uint16Selects 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 96.8
Control board boot) is required to 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.
