12.20 AI1 scaled at AI1 max
The default input for speed reference is analog input AI1. (This is controlled by the
parameters in group 22.)
Parameters 12.17 and 12.18 set the low and high limits of the analog input signal.
Scaling parameters 12.19 and 12.20 define the internal signal levels that correspond
to these limits as follows:
AI (scaled)
12.20
12.17
12.18
AI (mA/V)
12.19
The corresponding parameters for analog input AI2 are 12.27...12.30.
