Figure 9-46 Max. cable length as a function of the current drawn by the encoder system
In addition to the encoder systems for the supply voltage range of 4.75 V to 5.25 V in the diagram
above, encoder systems are also available for the extended range down to 3.6 V. These are
generally operable using encoder system cables up to 30 m in length, provided that the total
cross-section of the supply plus Remote Sense wires does not fall below 0.14 mm².

Description

Direct encoder systems outside the cabinet can be connected to the Sensor Module External
SME125. The SME125 evaluates these encoder systems and converts the calculated values to
DRIVE-CLiQ.
This component is always used when the temperature signals of the motors do not have safe
electrical separation or where this separation is not possible. SME125 is mainly used in linear
motor applications.
