INTRODUCTION
SD750 drives are compatible with several optional boards:
•Communication boards (Ethernet/IP, Profinet, CANopen…).
•Encoder board.
•Digital and analog I/O expansion boards.
•Optical fiberboard
…among others. Up to three optional boards can be connected, maximum two of the same type.
This manual focuses on the optional analogue input/output (I/O) expansion board. This board allows
to increase the number of analog inputs and outputs compared to those of the SD750.
This board allows the drive to increase its inputs and outputs as follows:
•increases two analog inputs, configurable with the same behavior as the standard analog input.
•Increases two analog outputs, with the same behavior as the serial analog output.
The front of the analog I/O expansion board is shown below:

INTRODUCTION
Analog I/O expansion board specifications
•Device type: I/O expansion
•Form factor: Insert card.
•Type of wiring: Preferably shielded hose
LED indicators
The analog I/O board expansion board includes 1 led indicator (status) that provides information about
the operation of the card. See section "Connectors description and led indicators" for more information.
It is green and its frequency changes according to the operating state of the system. Its operation is
explained in the following table:
LED
COLOR / FREQUENCY
DESCRIPTION
STATUS
Green / slow blinking
The system is operating correctly 1.
Green / fast blinking
Test mode. The user has put the board in test mode, it is useful
to locate the board when there are several identical boards.

When we state that the system operates correctly, it means that the communication between the expansion board, the
network controller and the central SD750 microcontroller is correct. This does not mean, however, that the
communication with the PLC is correct.

EN
CONNECTION TO THE DRIVE
The analog expansion board can be connected directly, through the connector on its back side, to any of
the three expansion connectors of the SD750 drive central control board. Once connected, it allows the
drive to be equipped with more analog input and output options and to display new parameter groups. Up
to two cards of this type can be connected to each drive.
Part Back of the board.
CAUTION
Power Electronics’ SD750 drives operate with high electric energy.
Make sure that the power has been disconnected and allow at least 10 minutes to ensure that the DC
bus has been discharged. Make sure with a multimeter that there is no voltage at the input, output or
DC bus before installing the expansion card. Otherwise, there is a risk of personal injury or accident

COMMISSIONING
COMMISSIONING
The analog I/O expansion card allows you to increase the number of inputs and outputs compared to the
standard SD750.
The following steps must be followed:
1. After stopping and de-energizing the drive, connect the expansion card to the connector of the
equipment prepared for the expansion cards that are free.
2. Check that the communication with the SD750 is correct (by displaying group G23.2). See that
the analog expansion board (A/B) status is activated (G23.2.5). Reference is made to a card A if
only one card is connected and B if there is a second card. In this case, new parameter groups
will be visible that will allow the adjustment and display of the expansion board status.
3. Set the inputs/outputs according to the desired behavior (G4.5, G4.6 or G8.5).
To see the measurement status of the analog input or output, see group SV3 (External display), values
belonging to EA4/EA5 for analog input and AO3/AO4 for the new analog outputs.
•Group SV3.13, SV3.16: Analog input status (format configurable in G4.5.3, G4.6.3, G4.7.3,
G4.8.3)
•Group SV3.26, SV3.28: Analog output status (format configurable in G8.4.2, G8.5.2, G8.6.2,
