Remedy: Check the following:
- Is the ambient temperatur
e within the de󹪝ned limit values?
- Have the load conditions and the load duty cycle been appropriately dimensioned?
- Has the cooling failed?
A30251 Power unit: Recti󹪝er overt
emperature
Message class: Power electronics faulted (5)
Message value: -
Component: Power Unit
Response: NONE
Acknowledgment: NONE
Cause: The alarm threshold for the overtemperature of the r
ecti󹪝er has been reached. The response is se
t using p0290.
If the temperature of the recti󹪝er increases by an additional 5 K, then fault F30037 is triggered.
Remedy: Check the following:
- Is the ambient temperatur
e within the de󹪝ned 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) recti󹪝er 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.
No
te:
- If the chip t
emperature 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 temperatur
e within the de󹪝ned 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 di󹪜er
ence between the po
wer 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
