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 vector control cannot be
applied.

Voltage boost at zero speed in percent of nominal motor
voltage.
Enables the motor model temperature adaptation. Estimated
motor temperature can be used to adapt temperature
dependent parameters (e.g. resistances) of motor model.
Temperature adaptation disabled.

Tunes the motor temperature dependence of stator
parameters (stator resistance).
Tuning factor.
Tunes the motor temperature dependence of rotor
parameters (eg. rotor resistance).
Tuning factor.
Activates or deactivates the hexagonal field weakening.
Deactivated. Use this for Ex motors.
Activated.
Selects the form for the U/f (voltage to frequency) ratio below
field weakening point. For scalar control only.
Linear ratio for constant torque applications.
Squared ratio for centrifugal pump and fan applications.
With squared U/f ratio the noise level is lower for most
operating frequencies. Not recommended for permanent
magnet motors.
