Parameters 161
Displays the value of analog input AI1 after scaling. See
parameters
and
.
This parameter is read-only.
-
-32768.000 …
32767.000
Scaled value of analog input AI1.
1 = 1
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
) is required to
validate any changes in the hardware settings.
V
Volts.
2
mA
Milliamperes.
10
Defines the filter time constant for analog input AI1.
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.
0.100 s
0.000 … 30.000 s
Filter time constant.
1000 = 1 s
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.

Defines the maximum site value for analog input AI1.
Set the value actually sent to the drive when the analog signal
from plant is wound to its maximum setting.
