Multiaxis Motor Control BoardFebruary 2014 Altera Corporation

Quadrature and Hall Effect Encoder Interface

The Multiaxis Motor Control Board allows you to connect two- and three-channel

quadrature encoders with RS485 interfaces.

IP cores in the FPGA on the host board decode the encoder signals.

HSMC Connector

The HSMC connector allows you to connect the Multiaxis Motor Control Board to an

FPGA host board.

f For more information on the HSMC connector, refer to the High Speed Mezzanine Card

(HSMC) Specification.

Table 5 lists the pin assignments for the HSMC connector. I/O direction is relative to

the Multiaxis Motor Control Board: input indicates input to the Multiaxis Motor

Control Board from the host board; output indicates an output signal from the

Multiaxis Motor Control Board to the host board.
