MODBUS COMMUNICATION
Introduction
To guarantee a correct operation of the drive, peripheral elements must be correctly selected and
properly connected. A wrong installation and / or application could cause a wrong operation of the system
or a reduction of the long life of the equipment, as well as damage to the components. This manual
should be read and understood carefully before proceeding.
The purpose of the Serial Communication Bus of the SD750 Kompakt drive is to integrate the drive itself
into a network compatible with the Modbus communications protocol. This is possible using the physical
communications ports RS485, Ethernet or USB port.
The Modbus communications system allows the SD750 Kompakt drive to be controlled and / or
monitored as a slave by a Modbus master from a remote location.
The RS485 network allows to connect up to 240 computers on the same network.
The SD750 Kompakt drive operates as a peripheral slave when connected to a Modbus system. This
means that the drive does not initiate the communication task, the master will start the task instead.
Virtually all of the drive operating modes, parameters and drive characteristics are accessible through
serial communications. As an example, the master can give command to start and stop the drive, check
the status of the SD750 Kompakt, read the current consumed by the motor, etc. The master mode can
access all the possibilities of the drive.
