What is the DC Bus voltage trip threshold for ATV11?

Input Voltage Overvoltage Trip Point
120 V single phase 355 Vdc 135 Vac
240 V single phase 370 Vdc 270 Vac
230 V three phase 380 Vdc 270 Vac

These values are the same whether the drive is running (ObF) or stopped (OSF).

The DC values are different because a single phase rectifier is less efficient than a three phase rectifier, and a voltage doubler is less efficient than a single phase rectifier.
