Sensorless vector control (SLVC)
Sensorless (field-oriented) vector control is based on a decoupled, separate control for the
torque-producing and the field-producing current component. In addition, the actual
speed is reconstructed by means of a motor model so that a speed sensor is not required.
In comparison to the V/f characteristic control without feedback, the following can be
achieved by means of sensorless vector control SLVC:
A higher maximum torque throughout the entire speed range
A higher speed accuracy
A higher concentricity factor
A higher level of efficiency
The implementation of torque-actuated operation with speed limitation
The limitation of the maximum torque in motor and generator mode for speed-
actuated operation
Tip!
If a high torque without feedback is to be provided at small speeds, we recommend
the "Sensorless vector control" operating mode.
Servo control (SC)
Field-oriented servo control (SC) is based on a decoupled, separate control of the torque-
producing and the field-producing current component. The operating mode is based on a
field-oriented, cascaded controller structure with feedback function and enables dynamic
and stable operation in all of the four quadrants.
The servo control basically offers the same advantages as the sensorless vector control
(SLVC).
