Select motor control
In
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
• 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
