1-5-4 Inverters
The maximum number of Inverters that can be connected to one Network depends on the PLC
model that is used, the remote I/O functions of the Inverter, and whether message communications
are used or not. (Use the message communications function for setting some parameters and for
monitoring the output current.) The differences between models are provided in the following tables.
