F2018 Device overtemperature shutdown
Overtemperature (heat sink) due to overload of
Ambient temperature too high. Specified
performance data are valid up to an ambient
temperature of 40 C.
Heat sink of device is dirty
Convection is prevented by other components or
mounting position of control cabinet
Failure of internal blower
Failure of air conditioning for control cabinet
Incorrect dimensioning of control cabinet with regard
to heat discharge
Supported by Firmware Variant:
Supported by Supply Unit:
The heat sink temperature of the device is monitored by a temperature
sensor and a temperature model. When the heat sink temperature has
reached the maximum value, the device is switched off in order to protect
it against destruction.
Before the error F2018 is triggered, the warning E2050 Device
overtemp. prewarning is output for 30 s.
Switch drive off and let it cool down. Check mechanical
system and drive dimensioning (working power mustn't
exceed, on average, continuous power of drive).
Reduce ambient temperature, e.g. by cooling the control
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
