10.2 Operating mode
Description
Via the mode of operation you select the control mode of the controller. You can choose
between
ƒ V/f characteristic control
ƒ Vector control
ƒ Sensorless torque control
The V/f characteristic control is the classical mode of operation for standard applications.
In comparison to the V/f characteristic control, with the vector control you obtain
improved drive characteristics by:
ƒ A higher torque throughout the entire speed range
ƒ A higher speed accuracy and a higher concentricity factor
ƒ A higher efficiency
