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.
KTY84
● p4601[0...n] to p4603[0...n] = 20 sets temperature sensor type KTY.
● If the value in parameter r4620[0...3] is not equal -200 °C, then the temperature display is
