4.1.1 Incremental encoder interface
The incremental encoder connections (ABZ channels and Hall signals) are made using the
15-pin D-type female connector X8. The encoder inputs (CHA, CHB and CHZ) accept differential
signals only. Twisted pairs must be used for each complementary signal pair e.g. CHA+ and
CHA-. The Hall inputs may be used as differential inputs (recommended for improved noise
immunity) or single ended inputs. When used as single ended inputs, leave the Hall U-, Hall V-
and Hall W- pins unconnected. 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 MotiFlex
e
100 to increase the encoder
supply voltage on pin 12 to maintain a 5 VDC supply at the encoder (200 mA max).
