Yaskawa iQpump1000 AC Drive Quick Start - Manual (Page 412)

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.
