Connecting The Encoders - HEIDENHAIN POSITIP 880 User Manual

Connecting the Encoders

POSITIP 880 can be used with HEIDENHAIN linear and rotary
encoders that provide sinusoidal output (11µApp or 1Vpp) or EnDat
(Encoder Data). The encoder inputs on the rear panel are designated
X1, X2, X3, X4, X5 and X6. See Fig. II.3 & Fig. II.4.
The connecting cable must not exceed 30 m (100 ft.) in length.
Do not engage or disengage any connections while the
unit is under power.
