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.

T = filter time constant
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.
