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 communication can be configured using one
master (PLC) 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 master communicates to the slave (drive) spec
ified. 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.
