FLUX CONTROLLER (MFC)
Group of parameters number [444]
Magnetic flux controller. Stable value of magnetic flux is required for the control. MFC is inactive in the field
weakening zone.

MFC damping [448]
Damping coefficient of the magnetic flux controller. Decreasing the value
increases the magnetic flux loop control speed at the cost of a higher
overshoot.

Flux
optimization
[924]
Rotor magnetic flux optimization.
□ Min. losses
Flux optimization is set to minimalize losses. However, the overal performance and the
dynamics of the motor can be decreased.
□ Max. torque
Flux optimization is set to maximalize the torque. Motor can be excited to high flux
levels.

SPEED CONTROLLER (SC)
Group of parameters number [445]
Speed controller. The feedback for closed vector control is taken from the parameter Speed source [1000]
(page 58). Open (sensorless) vector control uses mathematical model for speed/position calculation.

Frequency below which SC Dynamics 1 [457] (page 63) is used, SC Dynamics 2
[1128] (page 63) is used above this frequency. It is mainly used for increasing the
dynamics of speed control at low speed. By setting this to zero value, SC Dynamics 2
[1128] (page 63) will always be used.
