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 encoder board. The encoder board allows the SD750 to be
connected to an encoder to measure the speed of the motor it controls. This card has two channels for the
connection of this encoder, which will be essential to have for closed-loop controls.

INTRODUCTION
Encoder board specifications
•Device type: Encoder.
•Outputs for powering each encoder, programmable from 5VDC to 24VDC.
•Optical insulation between the encoder and the control board.
•Inputs for Channel A, /A, Channel B, /B and Channel Z, /Z (zero pass detection).
•Differential or ‘single-ended’ type inputs.
•Supports encoders with open collector output, voltage and ‘push-pull’.
LED indicators
The encoder 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.
