*3. After receiving data from the master inverter, the management inverter sends the next master switching com-
mand with a wait time of “silent interval + Communication Wait Time (y19).” If the management inverter cannot
receive the data sent from the master inverter within the Communication Error Timeout T
ime (y18), a commu-
nication timeout occurs and the management inverter follows the operation set in the Operation Selection on
Communication Error (y12).
*4. Be sure to enable the Communication Error Timeout Time setting (y18 = 0.01 to 99.99) on the management
inverter. When this setting is disabled (y18 = 0), the co-inverter communication will stop if the management
inverter cannot receive data from the master inverter. In this case, cycle the power supply for the manage-
ment inverter, or reset the management inverter (by turning ON/OFF the terminal RS).
