4.1.3 SinCos feedback

The SinCos connections (Sin and Cos incremental channels only) are made using the 15-pin D-type female connector X8. Twisted pair cables must be used for the complementary signal pairs e.g. Sin+ and Sin-. The overall cable shield (screen) must be connected to the metallic shell of the D-type connector. Connector X8 includes a ‘Sense’ pin, which is used to detect the voltage drop on long cable runs. This allows the MicroFlex e100 to increase the encoder supply voltage on pin 12 to maintain a 5V supply at the encoder (200mA max).
