The heat sink temperature of the device is monitored by a temperature
sensor and a temperature model. When the heat sink has become too
hot, the device is switched off in order to protect it against destruction.
Before the error

is triggered,
the warning

axis via the control unit in accordance with the process (e.g.
terminate processing, leave collision area etc.) or to reduce
the load of the drive controller.

Ambient temperature too high. Specified
performance data are valid up to an ambient
temperature of 40 C
Reduce ambient temperature, e. g. by cooling the
control cabinet
Heat sink of device is dirty
Clean heat sink
Convection is prevented by other components or
mounting position of control cabinet
Mount device vertically and provide sufficient space for
ventilating heat sink
Failure of internal blower
