The purpose of the Serial Communication Network of the SD300 is to
integrate the drive into a network compatible with the Modbus
communications protocol. This is possible using the RS485 physical
communications port or USB port.
Modbus communication system allows SD300 drives to be controlled and/or
monitored as a slave by a Modbus master from a remote location.
RS485 network allows connecting up to 16 equipment in the same network.
SD300 drives operate as a peripheral slave when connected to Modbus
system. This means that the drive does not start the communication task,
the master does.
Practically all of the operating modes, parameters and drive characteristics
are accessible through serial communications. For example, master can give
start and stop order to the drive, control SD300 status, read the current used
by the motor etc., in short, the master can access all of the features of the
drive.
