Description

Sensor Modules Cabinet-Mounted (SMC)
Cabinet-mounted Sensor Modules (SMC) can be ordered and configured separately. They
are used when a motor with a DRIVE-CLiQ interface is not available and when external
sensors in addition to the motor sensor are required. Only one sensor system can be
connected to each cabinet-mounted Sensor Module (SMC). Only sensor systems in which
the power supply for the sensor system is not grounded may be connected.
Note
The SMC supplies the power to the sensor; the SMC, however, must be provided separately
with 24 VDC power.
