- / real32 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. AI1 actual value 12.11
1000 = 1 mA or V /
1000 = 1 mA or V Value of analog input AI1. -22.000 ... 22.000 mA
or V
- / real32 Displays 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.
AI1 scaled value 12.12
1 = 1 / 1000 = 1 Scaled value of analog input AI1. -32768.000 ...
32767.000
V / uint16 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
96.8
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.
