C.1 MEMOBUS/Modbus Configuration

Drives can be controlled from a PLC or other master device via serial communications using the MEMOBUS/Modbus protocol.
MEMOBUS/Modbus communications can be configured using one master (PLC) and up to 255 slaves. The drive has slave

functionality only, and serial communication is normally initiated from the master and responded to by the slaves.
The master communicates with the specified slave drive. The address or node for each slave must be set prior so the master

can communicate with the slave at that address. A slave that receives a command from the master will perform the specified

function and send a response back to the master.
