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
and
. Those two points define a line which is extrapolated to the right and to the left.
• The special characteristic is activated by setting
= "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 (
) must be below 122 Ω to prevent the
triggering of sensor errors. In this case the temperature continues to be calculated.

Note!
• If a motor is selected from the motor catalogue, parameters
, and
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.
