Description
Configuration of standard analog inputs.
The true readings of the analog inputs can be
overridden for e.g. testing purposes. A forced value
parameter is provided for each analog input, and its
value is applied whenever the corresponding bit in
this parameter is 1.

Forced values selector for analog inputs AI1 and AI2.
Selects how the drive reacts when an analog input
signal moves out of the minimum and/or maximum
limits specified for the input.
The supervision applies a margin of 0.5 V or 1.0 mA to
the limits. For example, if the maximum limit for the
input is 7.000 V, the maximum limit supervision
activates at
7.500 V.
The inputs and the limits to be observed are selected
