Maximum Deadtime Compensation (B46) is the deadtime compensation used to compensate for dead-time effects in the inverter. This level of
compensation is used when the drive output current is above Current At Maximum Deadtime Compensation (B47). Both of these values related to
dead-time compensation are measured during auto-tuning and cannot be set by the user. It should be noted that if the auto-tuning test is not
performed and Maximum Deadtime Compensation (B46) = 0 then dead-time compensation is disabled. Although it is not recommended, it is possible
to disable dead-time compensation by setting Disable Deadtime Compensation (B48) = 1.
