When a drive with an internal rectifier is used this parameter should be left at zero. For a drive with an active external rectifier (used to control DC Bus
charging) this parameter should be the destination of the output of a variable selector set up for external rectifier monitoring. This allows the
monitoring block to prevent the drive from leaving the main loss ride through mode until the rectifier is fully active and phased forwards. If this feature
is not used the mains loss ride through mode ends as soon as the DC Bus voltage is above the mains loss detection level. The rectifier may still be
phasing forwards and the application of load at this point may cause the DC Bus voltage to fall back below the mains loss detection level again.
