Twisted pairs must be used for each complementary signal pair e.g. CHA+ and CHA-
or Data+ and Data-.
The overall cable shield (screen) must be connected to the metallic shell of the D-
type connector.
In Mint WorkBench, the primary motor feedback encoder on connector X8 is encoder
0. The extra incremental encoder input formed by digital inputs DI1 and DI2 is
encoder 1 (see page
66 ). The other extra incremental encoder input on connector X7
is encoder 2 by default (see page 83 ), but alternatively connector X8 can be
configured as encoder input 2 (see page 81 ).

Incremental encoder with Halls
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. The encoder supply on pin 12 typically provides 5.5 V
to the encoder (500 mA maximum, less if other encoder inputs are in use; see page
76 ). Maximum cable length is 30 m.
