Page 9: Introduction
POWER ELECTRONICS SD750 INTRODUCTION SD750 drives are compatible with several optional boards: • Communication boards (Ethernet/IP, Profinet, CANopen, Profibus…). • Encoder board. • Digital and analog I/O expansion boards. • Optical fiber board …among others. Up to three optional boards can be connected, maximum two of the same type. -

• GSD file PE_SD750.GSD. GSD File The GSD file contains information about the Profibus communication module installed in the equipment. When the Profibus network is configured, its software configuration requires a GSD file. ** To download the file, please contact Power Electronics. INTRODUCTION... -

When it is indicated that the system works correctly, it means that the communication of the Profibus board with the integrated communication chip and with the central micro of the SD750 is correct. This does not mean, however, that communication with the PLC is correct. -

SD750 drive. The Profibus expansion board allows to configure the SD750 as a slave to a PLC master using the Profibus industrial communication protocol. This communication allows to exchange information between both devices by configuring read and write variables. -
Page 13: Connectors Description
The following image shows a detailed distribution of the components of the optional Profibus board: On the Profibus board there are two connectors used to connect the board to the SD750 drive. In addition, there is a connector (SUB-D / F 9-pin) that is used for connection to the Profibus network. -

Load the GSD file into the PLC master. Once the GSD file is loaded, which allows us to introduce the SD750 device into a Profibus network, the configuration from the PLC master will indicate to the system how many variables are going to be shared, both writing variables (from the PLC to the SD750) and reading variables (from SD750 to PLC). - Page 15 POWER ELECTRONICS SD750 Type 4 Inputs and Screen Value Outputs Input 1 Status Comms 3584 Input 2 Motor Speed (%) 2002 Input 3 Motor Current 2006 Input 4 Motor Power 2009 Input 5 Motor Torque 2007 Input 6 Motor Frequency...
- Page 16 Connect communication wiring and ensure communication with the SD750 is correct (G23.3). Configure action in case of communication fault. Once the slave has been configured correctly, both in the PLC and in the SD750 itself, the connection may be made, and the configured variables will be shared.

Parameters setting The parameters that are activated once the board is connected are summarized below: NOTICE For more details about the Modbus address and value range, see the SD750 Drive Programming and Software Manual. Subgroup 20.2: Profibus The G20.2 group corresponds to the Profibus configuration parameters: NOTICE These parameters must match the configuration of the PLC. - Page 18 = Off NOTICE From version 6.0.0 of the SD750 and 2.0.0 of the Coin Profibus, these variables will have a default value belonging to the most probable configuration in the field. It is only necessary to define those input and output variables that have been configured in the master PLC.
