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 compensation
variation, called Gradient.

!
Both parameters are automatically measured during autotune procedure.
If required, it is possible to follow a procedure that allowos to compensate the IGBT
voltage output distortion; see section 7.3, IGBT Voltage Output Distortion.
