NOTICE
Damage to the encoder due to incorrect supply voltage
The encoder supply can be parameterized to 5 V or 24 V. Incorrect parameter assignment
can cause damage to the encoder.
• Select the appropriate supply voltage.
NOTICE
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.
