5.2 Select motor control

In C00006 the motor control is selected; the default is the servo control for synchronous motors.

Function extension from software version V3.0:

From software version V3.0, alternatively to the servo control also the V/f control and the sensorless

vector control are provided as control types in C00006

:

• The V/f control is the classic operating mode for standard applications.

• Compared to the V/f control, improved drive characteristics can be achieved with sensorless

vector control by:

• a higher torque across the entire speed range

• a higher speed accuracy and a higher concentricity factor

• Higher efficiency
