6.7.5 Dead Time
Compensation (uF.17)
The dead time compensation optimizes the switch-off times of the power module
semiconductors. Thus the motor posseses a better smooth running in the lower speed
range (especially at low carrier frequency).
When using sinusoidal filters Plus the dead time compensation must be disabled.
In case of poor supply connection or at IT-systems it may be necessary to switch
off the dead time compenstion.
Is a time during which the power modules of the inverter are blocked. This is, for
example, necessary before triggering the dc-brake to allow the de-excitation of the
motor.
