Unit Description / Notes
-999 to 999 Parameters P163 or P164 may be used to compensate a bias offset at
[ 0 ] the analog input signals, when the speed reference is given by the analog
1 inputs (AI1 to AI4).
Refer to figure 6.26.

NOTE!
In general, this parameter shall not be changed. Increasing the
speed filter value renders the system response slower.
