Motor temperature monitoring by means of other KTY types

Which products are affected?
9300vector 110…400kW SW8.0
9300 vector inverter (0.37..90kW) V8.1

Application:
Use of motors equipped with KTY temperature sensors in stator windings deviating from the Lenze standard.  

Description
In addition to the resistance/temperature characteristic of the KTY-83-110 which is usually used in combination with the Lenze motors it is now possible to select any characteristic. As a result, KTY types with different characteristics can now also be used.  
  • C1190 = 0: Fixed operating range for KTY83-110 in LENZE motors (Lenze setting)
  • C1190 = 1: Adjustable operating range (e. g. for KTY84-130)

Explanations concerning the diagram below
The operating range is defined by base values and nearly linear (a). It is interpolated between the values.
  • C1191/1: Setting of the lower temperature (T1)
  • C1191/2: Setting of the upper temperature (T2)
  • C1192/1: Setting of the lower resistance (R1) according to the KTY type used
  • C1192/2: Setting of the upper resistance (R2) according to the KTY type used
