NOTICE
Damage to the encoder due to incorrect supply voltage
The encoder supply can be parameterized to 5 V or 24 V. The sensor may be destroyed if
you enter the wrong parameters.
• Select the appropriate supply voltage.
NOTICE
Damage to motor in the event of incorrectly connected KTY temperature sensor
A KTY temperature sensor connected with incorrect polarity cannot detect if the motor
overheats. Overheating can cause damage to the motor.
• Connect a KTY temperature sensor with the correct polarity.
You can find information for parameterizing the KTY temperature sensor in the SINAMICS
S120 Function Manual (FH1) in Chapter "Monitoring and protective functions/thermal motor
monitoring".
