CONTROL SYSTEM
Switching between "isochroous" and "virtual droop" can be done with an external switch or through CAN
communication, while the engine is running. Selection of either one as default is allowed on customer's request.
Switching between "isochroous" and "virtual droop" can be done even while the engine is running. "Reverse droop"
can also be enabled or disabled with an external switch or through CAN communication while the engine is running.
Selection of "reverse droop enabled" or "reverse droop disabled" as default is allowed on customer's request.
The Isochroous-Virtual droop switching and reverse droop enabling/disabling connection diagram is shown
