Motor temperature monitoring (KTY) via encoder
The sensor type has to be selected in
C01190/2 .
• If the winding temperature detected via the motor temperature sensor reaches the limit value
set in C00121/2 (Lenze setting: 120 °):
• An advance warning in the form of the error response set in C00583/4 is issued.
• The " oH6: Motor temperature - MultiEncoder > C121 " error message is entered into the
logbook.
• If the fixed limit value of 150 °C is reached:
• The error response set in C00583/2 is triggered.
• The " oH12: Motor overtemperature - MultiEncoder " error message is entered into the
logbook.
• If open circuit is detected for the motor temperature sensor:
• The error response set in C00583/6 is triggered.
• The " Sd12: Thermal detector error - MultiEncoder " error message is entered into the logbook.
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 specific characteristic can be activated by selecting "1: Spec. characteristic" in C01190/1 for
the resolver and in C01190/2 for the encoder.
• In the Lenze setting, the specific characteristic is defined as follows:
