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.

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.
