4.2 List of faults and alarms
SINAMICS G120 CU250S-2 Control Units
1074
List Manual, 09/2017, A5E33842890
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?
A05001 (N)
Power unit: Overtemperature depletion layer chip
Message class:
Power electronics faulted (5)
Reaction:
NONE
Acknowledge:
NONE
Cause:
Alarm threshold for overtemperature of the power semiconductor in the AC converter has been reached.
Note:
- the response is set using p0290.
- if the temperature of the barrier layer increases by the value set in p0292[1], then fault F30025 is initiated.
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?

A05002 (N)
Power unit: Air intake overtemperature
Message class:
Power electronics faulted (5)
Reaction:
NONE
Acknowledge:
NONE
Cause:
For chassis power units, the following applies:
The alarm threshold for the air intake overtemperature has been reached. For air-cooled power units, the threshold is
42 °C (hysteresis 2 K). The response is set using p0290.
If the air intake temperature increases by an additional 13 K, then fault F30035 is output.
Remedy:
Check the following:
- is the ambient temperature within the defined limit values?
- has the fan failed? Check the direction of rotation.
A05004 (N)
Power unit: Rectifier overtemperature
Message class:
Power electronics faulted (5)
Reaction:
NONE
Acknowledge:
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?
A05006 (N)
Power unit: Overtemperature thermal model
Message class:
Power electronics faulted (5)
Reaction:
NONE
Acknowledge:
NONE
Cause:
The temperature difference between the chip and heat sink has exceeded the permissible limit value (blocksize
power units only).
Depending on p0290, an appropriate overload response is initiated.
