Description
Shows 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.
Forced value that can be used instead of the true reading of
the input. See parameter
Forced value of analog input AI1.
Selects the unit for readings and settings related to analog
input AI1.
Note: In firmware ASCL2 and ASCL4), this setting must
match the corresponding hardware setting on the drive
control unit. See chapter Electrical installation, section
Switches in the Hardware manual of the drive and the default
control connections for the macro in use in chapter
macros (page 55). Control board reboot (either by cycling the
power or through parameter
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.
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.
