Siemens SINAMICS S210 - Power Unit: Air Intake Overtemperature; Power Unit: Internal Overtemperature; Power Unit: Rectifier Overtemperature; Cooling Unit: Cooling Medium Flow Rate too Low

A05002 (N) Power unit: Air intake overtemperature
Message value: -
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: 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.
Reaction upon N: NONE
Acknowl. upon N: NONE
A05003 (N) Power unit: Internal overtemperature
Message value: -
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The alarm threshold for internal overtemperature has been reached.
If the temperature inside the power unit increases by an additional 5 K, then fault F30036 is triggered.
Remedy: Check the following:
- is the ambient temperature within the defined limit values?
- has the fan failed? Check the direction of rotation.
Reaction upon N: NONE
Acknowl. upon N: NONE
A05004 (N) Power unit: Rectifier overtemperature
Message value: -
Drive object: All objects
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?
Reaction upon N: NONE
Acknowl. upon N: NONE
A05005 Cooling unit: Cooling medium flow rate too low
Message value: %1
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: Cooling unit: Alarm - flow rate has fallen below the alarm value
