The output of the motor temperature is dependent from the selected motor en-
coder variant. In case of motors with an analog encoder (Ax, Bx), the tempera-
ture signal is output via the TP(+) und TP(-) ports in the power connection. In
case of motors with digital encoder (CS/CM), the temperature signal is transmit-
ted digitally via the encoder interface (cyclic communication).
The temperature of IndraDrive controllers is automatically evaluated via the
ACUROlink interface of the encoder. You will find information about interface im-
plementation in the manual of the encoder manufacturer, when using other con-
trollers.

4.2.4 Motor cooling
Self-cooling (IC410)
In case of self-cooling motors, the heat dissipation is realized via natural convec-
tion and radiation to the ambient air as well as by heat conduction to the ma-
chine construction.
The specified nominal data is reached at ambient temperatures of up to 40 °C.
Unhindered vertical convection has to be ensured by a sufficient distance of 100
mm to adjacent components.
Pollution of the surface of the motor reduces heat dissipation and can result in
thermal overload. The availability of the system can be increased by regular
checks and cleaning of the motors. Please ensure access to the motors for main-
tenance purposes.
