HEIDENHAIN POSITIP 880 - Connecting the Encoders

114 II Technical Information
II – 1 Installation and Electrical Connection
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.
Pin layout for encoder inputs
Do not engage or disengage any connections while the
unit is under power.
