If your motor is equipped with a temperature sensor, select the menu Parameters

parameters
W Temperature monitoring to enter the corresponding settings:
931e_294
In the Motor temperature field you can select, if no, an analog or a digital temperature
sensor is to be used.
Select digital motor temperature sensor , if the motor is equipped with a normally−closed
contact or a temperature sensor with PTC characteristic. The controller feeds the sensor
with a measured current. A voltage drop at the sensor will be detected and an
overtemperature error activated as a result.
For (in sections linear) analog temperature sensors, it is necessary to select the
temperature threshold. When the analog temperature sensor is activated, enter the
corresponding settings in the analog motor temperature field. Use the selection field to
choose one of the following temperature sensors:
ƒ KTY 81/82−210/220/250
ƒ KTY 81/82−110/120/150
ƒ KTY 83−110/120/150 (Lenze standard temperature sensor)
ƒ KTY 84−130/150
(
Stop!
The selection of a wrong temperature sensor will lead to a faulty evaluation of
the winding temperature. This may lead to the destruction of the motor!
