Sensor Module External; Sensor Module Sme 20/25; Sensor Module External 120/125 - Siemens SINAMICS S120 Function Manual

10.2.3.2

Sensor Module External

A Sensor Module External (SME) is required if the sensor interface is to be installed close to the
motor sensor outside a control cabinet. The SME has an IP67 degree of protection.
10.2.3.3

Sensor Module SME 20/25

The SME20 and SME25 evaluate encoder and sensor data. The calculated values are
transferred to the Control Unit via DRIVE-CLiQ. SME20 and SME25 differ regarding the
encoder interface.
A temperature sensor cannot be connected to the SME25 to sense the motor temperature.
Instead, use an SME125.
10.2.3.4

Sensor Module External 120/125

A Sensor Module External 120 (SME120) or Sensor Module External 125 (SME125) is required
for the following application conditions:
● The sensor interface is installed close to the motor outside a control cabinet
● Several motor temperature channels are required
● The motor temperature sensors do not have safe protective separation
● Safe protective separation is not possible.
SME12x has an IP67 degree of protection. SME12x are particularly suitable for linear and
torque motor applications.
If r0458[0...2].8 = 1, up to three temperature sensors can be connected at terminal block X200.
Each sensor is assigned to a temperature channel.
The SME12x evaluates the data of the temperature sensors and makes the calculated values
available via DRIVE-CLiQ for further processing.

Terminal Function
Temperature measurement
● p0600 = 1/2/3 selects the additional motor temperature measurement via channels 2 to 4.
● p0601 = 10 activates the evaluation via several temperature channels SME12x.
