Line Contactor Drop out
The controller will close the line contactor once a successful power up sequence has been carried
out, after which drive operation can be achieved. The line contactor will remain closed unless it is
opened following a serious fault or power being disconnected.
A further configurable option is available where the line contactor is opened (dropped out) if no
drive activity has occurred for a period exceeding the Line Contactor Dropout Timer personality.
If drive operation is selected once the line has been opened then it will be closed again so that
drive operation can occur. Line contactor dropout operation can be enabled or disabled in the
setup menu.
