Dependency:
-The actual maximum output voltage depends on the actual incoming line supply voltage.
-The maximum possible output voltage r0071 of the drive inverter is determined by the DC link voltage r0026 and the maximum modulation depth P1803 in the gating unit.
-The maximum output voltage r0071 is tracked with the DC link voltage so that the highest possible value is always and automatically achieved.
-The output voltage only reaches the calculated maximum value under
