INVERTER PARAMETERS
Serial line
The inverter can communicate with a remote controller through a RS-485 2-wire serial line. In this case, the inverter behaves like
a "slave", i.e. it answers on special controller request only (master). Up to 32 inverters can be parallel connected with addresses
set between 1 and 99 through P - 68.
The address 99 is a specialized one since it is expected that it will be used when it is necessary to send a code to all inverters
simultaneously; in this case the reception of the code is assured to all inverters regardless of the individual address, the
acknowledgement will be made only from the inverter with address 99.
The serial line allows to read and write all the parameters, forcing the various controls by replacing the keyboard or the terminal
board, or forcing the I/O as in a PLC. The parameters involved are:
