5.9.3.1 Specific characteristic for the motor temperature sensor

A specific characteristic can be defined and activated for the motor temperature sensor if required.

• The specific characteristic is defined on the basis of two grid points which must be set in C01191

and C01192

. Those two points define a line which is extrapolated to the right and to the left.

• The special characteristic is activated by setting C01190

="1".

• In the Lenze setting, the specific characteristic is defined as follows:

[5-37] Lenze setting of the specific characteristic

The following applies from software version V4.0:

• Sometimes a short circuit is a desired state (e.g. temperature contact closed below 140 °C). For

this purpose, the interpolation point 1 (C01191/1

) must be below 122 Ω to prevent the

triggering of sensor errors. In this case the temperature continues to be calculated.

• Interpolation point

• C01191/1

= 25 °C

• C01192/1

= 1000 Ω

• Interpolation point

• C01191/2

= 150 °C

• C01192/2

 Note!

• If a motor is selected from the motor catalogue, parameters C01190, C01191, and

C01192

are overwritten!

• If the controller measures a resistance below 122 Ω, this is interpreted as a sensor

error and a temperature of 255 °C is output.
