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 61xx 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 MP2220.

a. The control assigns the EnDat clock to pin 14. Therefore, you must not assign any signals
to this pin when using the TTL adapter connector.
