C.1 MEMOBUS/Modbus Configuration
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 and a maximum of 255 slaves. The drive has
slave functionality only, meaning that serial communication is normally initiated from the master and responded to by the
slaves.
The address or node for each slave must be set beforehand so that 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 then send a response
back to the master.
