Figure 3-5: Encoder Feedback Signals
Please note that the voltage across each differential pair of
encoder input signals (EA+, EA-), (EB+, EB-) and (EZ+, EZ-)
should be at least 3.5V or higher. Therefore, the output current
must be observed when connecting to the encoder feedback or
motor driver feedback as not to over drive the source. The differ-
ential signal pairs are converted to digital signals EA, EB and EZ
and then fed to the FPGA.
Below are examples of connecting the input signals with an exter-
nal circuit. The input circuit can be connected to an encoder or
motor driver, if it is equipped with: (1) a differential line driver or (2)
an open collector output
Connection to Line Driver Output
To drive the SSCNET board encoder input, the driver output must
provide at least 3.5V across the differential pairs with at least 6 mA
driving capacity. The ground level of the two sides must also be
tied together.
