Vector Control
Vector control (field-oriented control) is a high-performance control type for induction
machines. It is based on an exact model calculation of the motor and two current
components that simulate and accurately control the flux and torque by means of software
algorithms, thereby enabling predefined speeds and torques to be observed and limited
accurately and with a good dynamic response.
Two vector control types exist:
Frequency control (–> "Sensorless Vector Control") and speed-torque control with speed
feedback (–> "Sensor").
Status Word
Bit-coded -> "Process data" word, transmitted by -> "PROFIdrive" at cyclic intervals to
control the drive states.
