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.
This manual focuses on the optional Profibus expansion board. This board allows the equipment to
be integrated into Profibus communication network in a comfortable and simple way.
It has been designed to provide information about its operational status at any time.
Below is the front of the Profibus expansion board:

LED Indicator
The profibus expansion board has one led indicator on the top of the board, which provides information
about the status. Note that the led is bi-color and will change its color and frequency according to the
situation.
Refer to the following table for the description of all the possible colors and frequencies of the led
indicator, as well as what they represent.
LED

DESCRIPTION
STATUS
Red, steady
Hardware failure or inability to install the protocol.
The board probably has to be repaired.
Red, slow flashing
The board cannot stablish communication with the
network controller or initialize the protocol.
Red, fast flashing
The board cannot stablish communication with the
SD750 central board.
Green, slow flashing
The system is operating correctly.1.
Green, fast flashing
Test mode. User has set the board to test mode.

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.

CONNECTION TO THE DRIVE
CONNECTION TO THE DRIVE
The Profibus expansion board connects directly, via the sixteen-pin ID connector on the back, to any of
the three expansion connectors on the central control board of the 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.
CAUTION
Power Electronics’ SD750 drives operate with a high electric energy.
Make sure the power has been turned off and wait at least 10 minutes to ensure that the DC bus has
been discharged, make sure with a multimeter that there is no input, output or DC bus voltage before
installing the expansion board. Otherwise, there is a risk of personal injury or accident.

Connectors Description
The Profibus connection is made using a standard 9-pin SUB-D connector according to the definition of
the EN 50170 standard. The wiring for the nine-pin connector is shown in the figure below:
Connection Scheme
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.

COMMISSIONING
COMMISSIONING
Follow the next steps to carry out the commissioning of the Profibus board:
1. 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). Depending on the GSD loaded, the number of inputs and outputs and the possibility to
select the content of these variables will vary. There are five different types of configuration of inputs
and outputs:

COMMISSIONING
2. Configure network parameters (G21, see section “Parameters setting”) so they match with the data
expected by the master.
3. Configure the Profibus slave on the PLC master (network configuration and number of shared
variables).
4. Configure the Profibus slave on the SD750 (network and Custom Modbus configuration associated
with the shared variables).
5. Connect the Profibus board and check its status and communication.
6. Verify communication is stablished. Configure action in case of communication faults with the
master.
7. 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.
The rest of the commissioning depends on the PLC, the program used, etc.

Fault
The drive will trigger fault F113: Lost PBUS c1 comms when communication is
not enabled.

case of incorrect communication, the user can select whether a fault appears or is ignored.

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.

G20.6.1 Custom
modbus addr 1 = 0
0 to 65535
These parameters allow configuring 120 consecutive registers (4500 to 4619) variables from the
Modbus map as required. This is particularly useful when designing a SCADA, so that the client
can consult several registers in a single reading operation.
They are grouped as follows:
•Subgroup 20.6.1: Values 1 to 30
•Subgroup 20.6.2: Values 31 to 60
•Subgroup 20.6.3: Values 61 to 90
•Subgroup 20.6.4: Values 91 to 120
In parameters G20.6.x, user must enter the Modbus registers (Modbus address –40001) that will
be pointed to. Once configured, parameters G20.7.x can be used to read or write the value of
each register.
Example: Let us suppose we want to store the local speed reference (G3.3, Modbus 40053). We
must configure register 52 (40053 –1) in G20.6.1, at Custom modbus addr1.
Then, in G20.7.1, Custom modbus val 1 we will read the current value of the local speed reference.
To modify it, we must enter the new value and save changes.
Note: When reading or writing a variable, keep in mind the type of variable and its Modbus range
to ensure values are interpreted correctly.
