Temperature sensor connection
Damage to motor due to incorrectly connected KTY temperature sensor
If a KTY temperature sensor is connected with incorrect polarity, it is not possible to detect
when the motor overheats. Overheating can cause damage to the motor.
• Connect a KTY temperature sensor with the correct polarity.
Details on the parameterization of the KTY temperature sensor can be found in the
SINAMICS S110 Function Manual.
Note
The maximum length of the temperature sensor cable is 100
m. The cables must be
Danger to life due to electric shock caused by sparkovers to the temperature sensor cable
Sparkovers in the signal electronics can occur in motors without safe electrical separation
of the temperature sensors.
• Only use temperature sensors that fully comply with the specifications for safe
separation.
• If safe electrical separation cannot be guaranteed (for linear motors or third-party
motors, for example), use a Sensor Module External (SME120 or SME125) or a
Terminal Module TM120.
