VFCPLUS
VFCPLUS is a high-performance control mode that can operate asynchronous motors and reluctance motors with very high torque dynamics with or without a rotary encoder.
The control mode can be operated as speed or torque control. This control mode calculates all important state variables for controlling the motor by using a motor model. Typical applications for the VFCPLUS control mode are speed-controlled asynchronous machines with high demands on the speed and torque stability.
