9.5.3.2
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.
9.5.3.3
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.
9.5.3.4
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.
