Description
Defines the relative output voltage boost at zero speed (IR
compensation). The function is useful in applications with a
high break-away torque where direct torque control (DTC
mode) cannot be applied.

Selects whether the temperature-dependent parameters
(such as stator or rotor resistance) of the motor model adapt
to actual (measured or estimated) temperature or not.

Activates hexagonal motor flux pattern in the field weakening
area, ie. above the limit defined by parameter
Hexagonal field weakening
Note: This parameter is only effective in scalar motor control
mode.

The rotating flux vector follows a circular pattern.
The flux vector follows a circular pattern below, and a
hexagonal pattern above, the hexagonal field weakening point
