Temperature sensor connection
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.
Note
The maximum length of the temperature sensor cable is 100 m. The cables must be shielded.
Electric shock in the event of voltage flashovers at the temperature sensor
Voltage flashovers in the signal electronics can occur in motors without safe electrical
separation of the temperature sensors.
● Use temperature sensors that comply with the specifications relating to protective
● If safe electrical separation cannot be guaranteed (for linear motors or third-party motors,

Type: Screw terminal 2
The maximum cable length that can be connected is 30 m.
Note
The two "+" and/or "M" terminals are jumpered in the connector. This ensures that the supply
voltage is looped through.
