6.2 Select motor control
In C00006 the motor control is selected; the default is the servo control for synchronous motors.
Alternatively to the servo control, also the V/f control and the sensorless vector control are provided
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
