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 optical fiber expansion board. This board is optional for the SD750
variable speed drives frame 1 to 8; in the case of the SD750 frame 9 to 11, is included on the
standard equipment.
This board allows integrating the drives in optical fiber networks in a comfortable and simple way. Its
practical design allows to know the board's operating status at all times.
Below is the front of the optical fiber expansion board:
Optical fiber board specifications
•Compatibility: SD750.
•Baud rate: Speed is fixed and not configurable.

CONNECTIONS
Connection to the drive
For the variable speed drives frame 1 to 8, the optical fiber must be connected 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.
In the case of the variable speed drives frame 9 to 11, the optical fiber board must be connected to the
specific connector of the expansion board shown below.

CONNECTIONS
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.
For drives frame 9 to 11, the modules connection kit provided with the drive must be installed.
Connection between modules
Follow the next electrical schemes to connect up to 4 modules of Power Electronics SD750 variable
speed drives.

COMMISSIONING
COMMISSIONING
An example of the fiber optical board commissioning is described below.
1. Set in G1.9 Master/Slave = “Enable”, to activate this functionality.
2. Once parameter G1.9 has been configured, group G25 is activated for configuration.
3. Set in G25.1 if the team role is Master or Slave.
4. Configure the G25.2 Run fiber: Set it to YES if it is desired that the slave takes the run command
sent by the Master when it receives it. When configured as NO, the slave will also need a start
command (normally simultaneous to the one that comes to the Master to start at the same time;
only in small exceptions will not need to start at the same time).
5. Configure the G19.1.1 Type of control based on the chosen control.
Parameters setting
The parameters that are activated once the board is connected are summarized below:

MASTER (there can only be one), and a SLAVE (there can be several). The connection between
the equipment by optical fiber is needed.
