27.11Encoders

27.11.1 Position encoders

See “X1 to X6, X35 to X38, X201 to X214: Position encoder 1 VPP” on page 27 – 457.

Especially for machine retrofits, the use of adapters for encoder signal adjustment can be of

interest.

Encoder signals with 11 µA

or TTL level can be adapted to the 1 V

interface with

HEIDENHAIN adapter connectors.

Note

Please note:

 The adapters adjust only the levels, not the signal shape.

 The contamination signal of the square-wave encoder cannot be evaluated.

 A square-wave signal can be subdivided no more than 4-fold.

 If encoders with TTL signals are connected to a CC 424 (B) via an adapter (ID 317505-xx),

then the phase position of the reference pulse is not correct. In order to deactivate

monitoring, set bit 9 of MP 2220.
