Menu 3: Regen sequencer

In regen mode the drive assumes the mains is lost, it does not 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 Regen drive main contactor is opened.
The Regen drive also monitors the voltage at it's AC terminals (U, V and W) for mains loss and if this falls below the levels given in the table the unit
is disabled and the Regen drive main contactor is opened.
