Encoder Axis

In the TwinCAT context, one speaks of an encoder axis if a pure encoder system is to be integrated into the system as an axis object.

Encoder axes do not have "Drive" or "Ctrl" as sub-elements of the axis.

An encoder axis can be used in the system as master of couplings, but never be slave.

A special feature of the encoder axis is that the setpoint corresponds to the actual value, since this axis type does not have its own setpoint generator. If couplings are set up with an encoder axis, they are therefore indirectly coupled to the actual value (couplings in the TwinCAT system are always setpoint-based).

This leads to the fact that a noise component is to be seen in the setpoint and is also transferred to slave axes.
