4-8 Feedback MN1942

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 beused for the c omplementary signal
pairse.g. Sin+ and Sin -.The ov erall cable shield (screen) must be connec ted tothe met allic shell
ofthe D-type connec tor.Connec tor X8 includes a ‘Sense’ pin, which is usedtodetect the voltage
dropon long cable runs . This allows the MicroFlex e100 toincrease the encoder supply voltage
onpin 12 to maintain a 5V s upply at the encoder (200mA max).
