Technical data

The coolant inlet temperature must be set in a temperature range
of +10°C - +40°C and may be only max. 5°C under the existing
ambient temperature to avoid condensation.
9.12 Motor Temperature Overview
9.12.1 General
The motor temperature overview occurs via two – independent of each other -
working systems.
● Temperature sensor
● Temperature Model
and ensures, therewith, the highest protection of the motors against irreversible
damage by thermal overload.
9.12.2 Temperature sensor
The motor temperature overview is ensured via the temperature sensor of type
KTY84, which is built into the stator. The measured motor temperature is con-
trolled via the following marginal values:
● Motor-warning temperature (140°C)
● Motor-disconnection temperature (150°C)
The marginal values are filed within the encoder memory of the MSK motors.

The IndraDrive drive devices overview the functionality of the temperature sen-
sors.
