7.1 Operating mode
Description
The control mode of the controller can be selected via the operating mode. You can select between
·
V/f characteristic control
·
Vector control
·
Sensorless torque control
Selection of the correct operating mode
V/f characteristic control is the classic operating mode for standard applications.
The vector control provides a better control performance than the V/f characteristic control due to:
·
a higher torque over the whole speed range
·
a higher speed accuracy and concentricity factor
·
a higher efficiency
