Function
With C030a (C073a, C116a)=other than 0: Disabled, the motor field weakening
follows a law optimizing the output voltage based on the available DC voltage
(“automatic” field weakening).
This parameter defines the trip rate of the automatic field weakening regulator.
For more details, see Field Weakening (VTC and FOC Only).

Function
If it is not set to zero, this parameter determines the speed value to be entered for the
maximum speed alarm (A076).

Function
If the V/f curve pattern C013 (C056, C099) = Quadratic, this parameter defines the
maximum voltage reduction in terms of theoretical
V/f pattern, which is
implemented at the frequency programmed in C033 (C076, C119).

Function
If the V/f curve pattern C013 (C056, C099) = Quadratic, this parameter defines
the frequency implementing the max. torque reduction in terms of theoretical
V/f
pattern set in C032 (C075, C120).
