1.4.2 Dead Time Comp
The Dead time comp function allows for compensation of the output voltage distortion due to IGBT voltage
drop and its switching characteristics. Distortion of output voltage may cause non uniform, non smooth shaft
rotation in open loop V/f control or in a closed loop Sensorless Vector control mode errors in speed estimation
especially at very low speeds.Through the two parameters it is possible to set a voltage value and the compen-
sation variation, called Gradient.
