82 Electrical installation: input / output
The inputs may be used as differential inputs (recommended for improved noise
immunity) or single ended inputs. When used as single ended inputs, leave the
CHA-, CHB- and CHZ- 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
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.
