Temperature sensor

The motor temperature is monitored by the two independently operating sys‐
tems
● Temperature sensor
● Temperature model
and thus the highest possible protection of the motors against irreversible
damage caused by thermal overload is ensured.
The monitoring of the motor temperature is ensured via the temperature sen‐
sor of the KTY84 type, which is built into the stator. The measured motor
temperature is monitored for the following threshold values:
● Motor-warning temperature (140 °C)
● Motor shutdown temperature (150 °C)
The threshold values are stored in the encoder data memory of the MSK mo‐
tors.

The IndraDrive control devices monitor the functionality of the temperature
sensors.
For more information, please refer to the functional description for IndraDrive
controllers.
