WARNING
The built-in KTY temperature sensor protects the motors against overload up to I
max
.
There is no adequate protection for thermally critical load situations, e.g. a high overload at
motor standstill. For this reason, additional protection in the form, for example, of a thermal
overcurrent relay must be provided.
The temperature sensor is designed so that the DIN/EN requirement for "protective
separation" is fulfilled.
WARNING
If the user carries out an additional high-voltage test, then the ends of the temperature
sensor cables must be short-circuited before the test is carried out! If the test voltage is
connected to a temperature sensor terminal, then it will be destroyed.

Encoder (option)
The encoder is selected in the motor Order No. (MLFB) using the appropriate letter at the 9th
position.
Note
The letter ID at the 9th position of the Order No. (MLFB) differs for motors with and without
DRIVE-CLiQ.
