motor voltage.
0.00 ... 50.00 %
Disabled / uint16Selects whether the temperature-dependent
parameters (such as stator or rotor resistance) of the
motor model adapt to actual (measured or estimated)
temperature or not.
See parameter group 35 Motor thermal protection for
selection of temperature measurement sources.

Off / uint16Activates hexagonal motor flux pattern in the field
weakening area, i.e. above the limit defined by
parameter 97.19 Hexagonal field weakening point.
Note: This parameter is only effective in scalar motor
control mode.

120.0 % / real32Defines the activation limit for hexagonal field
weakening (in percent of the field weakening point, i.e.
the frequency at which maximum output voltage is
reached). See parameter 97.18 Hexagonal field
weakening.
