◆ H5: MEMOBUS/Modbus Serial Communication

Serial communication is possible in the drive using the built-in RS-422/485 port (terminals R+, R-, S+, S-) and
programmable logic controllers (PLCs) or similar devices running the MEMOBUS/Modbus protocol.
The H5- parameters are used to set up the drive for MEMOBUS/Modbus Communications. Refer to
