Fig. 33: Sending output data to the inverter and saving them temporarily
When a new Sync command is issued, all inverters simultaneously update their active setpoints
with the value temporarily stored before (Fig. 34). In other words, the active setpoints are not
updated until the new Sync command has been received. The inverters quit Sync mode when the
Unsync control command is issued.
