11.3 Faults and alarms
Remedy:
Check the following:
- Is the ambient temperature within the defined limit values?
- Have the load conditions and the load duty cycle been appropriately dimensioned?
- Has the cooling failed?
A30251
Power unit: Rectifier overtemperature
Message class:
Power electronics faulted (5)
Message value:
-
Component:
Power Unit
Response:
NONE
Acknowledgment: NONE
Cause:
The alarm threshold for the overtemperature of the rectifier has been reached. The response is set using p0290.
If the temperature of the rectifier increases by an additional 5 K, then fault F30037 is triggered.
Remedy:
Check the following:
- Is the ambient temperature within the defined limit values?
- Have the load conditions and the load duty cycle been appropriately dimensioned?
- Has the fan failed? Check the direction of rotation.
- Has a phase of the line supply failed?
- Is an arm of the supply (incoming) rectifier defective?
A30252
Power unit: Chip overtemperature alarm
Message class:
Power electronics faulted (5)
Message value:
Power semiconductor: %1, temperature: [0.01 degrees C] %2
Component:
Power Unit
Response:
NONE
Acknowledgment: NONE
Cause:
The chip temperature of the power semiconductor involved has exceeded the permissible alarm threshold.
Note:
- If the chip temperature of the power semiconductor involved increases by 5K, then fault F30025 is initiated.
Alarm value (r2124, interpret hexadecimal):
yyyyxxxx hex: yyyy= Power semiconductor, xxxx = Temperature in 0.01°C
Remedy:
Check the following:
- Is the ambient temperature within the defined limit values?
- Have the load conditions and the load duty cycle been appropriately dimensioned?
- Has the cooling failed?
- Pulse frequency too high?
A30253
Power unit: Overtemperature thermal model alarm
Message class:
Power electronics faulted (5)
Message value:
Power semiconductor: %1, temperature: [0.01 degrees C] %2
Component:
Power Unit
Response:
NONE
Acknowledgment: NONE
Cause:
The temperature difference between the power semiconductor involved and the heat sink has exceeded the permissible
alarm threshold.
The maximum output current is reduced as overload response.
Alarm value (r2124, interpret hexadecimal):
yyyyxxxx hex: yyyy= Power semiconductor, xxxx = Temperature in 0.01°C
