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 F2018 Device overtemperature shutdown is triggered,
the warning E2050 Device overtemp. Prewarning is output.
When the warning E2050 appears, it is possible to stop the
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.
Switch drive off and let it cool down, check mechanical
system as well as drive dimensioning (working power
mustn't exceed, on average, continuous power of drive)
Reduce ambient temperature, e. g. by cooling the
control cabinet
Clean heat sink
Mount device vertically and provide sufficient space for
ventilating heat sink
If blower fails, replace device or power section
Check air conditioning of control cabinet
Check dimensioning of control cabinet
