Figure 5-5 Menu 3 Regen logic diagram
In Regen mode the drive assumes the mains is lost and does cannot close the input and does not attempt synchronisation if the DC bus voltage is
below the levels given in the table below. If the unit is synchronised and the DC bus voltage falls below this level the unit is disabled and the input
contactor is opened. The Regen unit also monitors the voltage at its AC terminals for mains loss and if this falls below the levels given in the table the
unit is disabled and the input contactor is opened.
