Serial communication
The AC drive provides possibility for different types of serial
communication.
•
Modbus RTU via RS232/485
•
Fieldbuses as Profibus DP and DeviceNet
•
Industrial Ethernet as Modbus/TCP, Profinet IO,
EtherCAT and EtherNet/IP
9.1
Modbus RTU
Use the isolated RS232/485 option board for serial
communication. This port is galvanically isolated.
The protocol used for data exchange is based on the Modbus
RTU protocol, originally developed by Modicon.
The
physical connection is RS232/485. The AC drive acts as a
slave with selectable address in a master-slave configuration.
The communication is half-duplex. It has a standard non
return zero (NRZ) format.
The baud rate is adjustable between 2400 to 38400.
The character frame format (always 11 bits) has:
•
one start bit
•
eight data bits
•
two stop bits
•
no parity
The AC drive has also an asynchronous serial
communication interface behind the control panel.
Please note that this port is not galvanically isolated.
It is possible to temporarily connect a personal computer
with for example the software EmoSoftCom (programming
and monitoring software) to the RS232 connector on the
control panel. This can be useful when copying parameters
between AC drives etc. For permanent connection of a
personal computer you have to use one of the
communication option boards.

Parameter sets
Communication information for the different parameter
sets.
The different parameter sets in the AC drive have the
following DeviceNet instance numbers, Profibus slot/index
numbers, Profinet IO index and EtherCAT index numbers:
Parameter set A contains parameters 43001 to 43899. The
parameter sets B, C and D contains the same type of
information. For example parameter 43123 in parameter set
A contain the same type of information as 44123 in
parameter set B.
NOTE: This RS232 port is not isolated.
WARNING!
Correct and safe use of a RS232
connection depends on the ground pins of
both ports being the same potential.
Problems can occur when connecting two
ports of e.g. machinery and computers where both
ground pins are not the same potential. This may
cause hazardous ground loops that can destroy the
RS232 ports.
The RS232 connection behind the control panel is not
galvanically isolated.
The RS232/485 option board from CG Drives &
Automation is galvanically isolated.
Note that the control panel RS232 connection can
safely be used in combination with commercial
available isolated USB to RS232 converters.
