It is possible to connect EnDat encoders to all position encoder inputs of an MC or CC!
EnDat encoders
EnDat encoders offer the possibility of storing machine or system-dependent data in the

Note
Current MCs and CCs feature so-called "Polyfuses". These are electronic fuses that
separate defective peripheral devices from the low voltages in the control in the event of an
error. This is also true for the encoders!
If a defective encoder draws too much current, it is "separated" from the control component.
Corresponding error messages are displayed.
