4.1.4 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
e
100 to increase the encoder supply voltage
on pin 12 to maintain a 5 V supply at the encoder (200 mA max). The Sin and Cos channel input
circuits accept a nominal 1 V pk-pk sine wave centered on a 2.5 V reference.
