Device Overtemperature Shutdown
Description:
- Overtemperature (heat sink) due to overload of device
- Ambient temperature too high. Specified performance data is valid up to an ambient temperature of 40 °C
- Heat sink of device is dirty
- Convection is prevented by other components or mounting position in control cabinet
- Device-internal blower failed
- Failure of air conditioning for control cabinet
- Incorrect dimensioning of control cabinet with regard to heat dissipation
- For liquid-cooled devices: No cooling system connected
- For liquid-cooled devices: Error in cooling system, e.g. coolant pump defective or filter clogged; thereby flow rate too small / inlet temperature of coolant too high
- Switch drive off and let it cool down. Check mechanical system and drive sizing (on average, working power may not exceed continuous power of drive) For liquid-cooled devices: Check dimensioning of cooling system (see documentation with part number R911309636)
- 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
- Connect cooling system
- Check cooling system and remove error
