1-3-4 Inverter
The maximum number of Inverters that can be connected to one Network depends on the PC 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.
