Typical examples of network use:
PC (master) for the parametrization of one or several inverters at the
same time;
SDCD monitoring inverter variables;
PLC controlling the operation of one or more inverters in a industrial
process.
8.19.2 Interfaces Description
The physical connection between the inverters and the master is performed
according to one of the standards below:
a. RS-232 (point-to-point up to 10m);
b. RS-485 (multipoint, galavanic isolation, up to 1000m);
8.19.2.1 RS-485
This interface permits the linkage of up to 30 inverters to a master (PC,
PLC, etc.), attributing and setting for each inverter an address (1 to 30). In
addition to these 30 addresses, there are two addresses to perform special
tasks:
Address 0: any inverter in the network is inquired, independently of its
address. Only one inverter can be connected to the network (point-to-
point) in order to prevent short-circuits in the line interface.
