Sensor Modules External (SME)
Measuring systems outside the cabinet can be connected directly to the Sensor Module
External (SME). The SME evaluates these measuring systems and converts the calculated
values to DRIVE-CLiQ. No motor or sensor data is stored in the SME.
Note
The SME supplies the power to the sensor; the SME, however, must be provided separately
with 24 VDC power. The power is supplied to the SME from the connected DRIVE-CLiQ
cable. This must be taken into consideration when the DRIVE-CLiQ cable is selected.
