Special feature in the case of linear motors
The motor encoder (linear scale) of linear motors also acts as load measuring system. Only one
measuring system is required for this reason. The system is connected by means of a Sensor
Module or directly via DRIVE-CLiQ.

Figure 4-28 Example of a single-encoder system
2-encoder system
The failsafe actual values for a drive are provided by 2 separate encoders. The actual values
are transferred to the Control Unit via DRIVE-CLiQ.
For motors without a DRIVE-CLiQ interface, the connection is made using additional Sensor
Modules (see encoder types).
