OPERATION WITH MODBUS RTU
LEROY-SOMER
19 - OPERATION WITH MODBUS
RTU
19.1 - Serial link
The PROXIDRIVE incorporates as standard an RS485/2 wire
serial link port accessible with an RJ45 connector.
19.1.1 - Location and connection
19.1.2 - Protocols
The drive handles the following protocols:
- Modbus RTU
- LS Net
The drive automatically recognises the protocol used, and
this can be read in

"Serial mode".
19.1.3 - Parameter setting
Depending on the application, the following parameters need
to be modified.

19.1.4 - Networking
The PROXIDRIVE serial port allows the drive to
communicate with an RS 485 2 wire network.
• The network should therefore be connected in a "daisy-
chain" (not a star).
• At minimum, terminals 2, 3, 7 and the shielding must be
connected.
The CT Comms cable option allows a PC to be connected
directly to the PROXIDRIVE. This cable, with a SUB-D 9
connector at one end and RJ45 at the other, incorporates an
isolated RS232/RS485 converter.
CAUTION:
Do not use this cable to network several PROXIDRIVEs
("24Vs" should not be connected).
19.2 - Parameter setting using the PC
With PROXISOFT parameter-setting software, setting up the
PROXIDRIVE from a PC is very user-friendly.
- Quick configuration: the drive parameters are set very
quickly from a "quick configuration" screen.
- Supervision during commissioning: used to supervise the
various data relating to operation on a single screen.
- File storing: used to save all the parameter files thus
enabling very quick duplication of an already existing setting.
To connect the PC to the PROXIDRIVE, use the CT Comms
cable option described above or use a RS232/RS485 2 wire
converter (example: Amplicon 485 FI).
For PCs equipped with USB ports, ask your usual LEROY-
SOMER contact.
19.3 - Control word and status word
PROXIDRIVE run commands can be managed by a single
parameter

, called the "control word".
In fact, the value of

corresponds to a word in which each
bit is associated with a command. The command is enabled
when the bit is at 1, and disabled when the bit is at 0.
To enable commands with a control word, configure
