4 Faults and alarms
4.2 List of faults and alarms
A05002 (N)
Power unit: Air intake overtemperature
Message value:
-
Message class:
Power electronics faulted (5)
Drive object:
B_INF, VECTOR_G
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:
-
Message class:
Power electronics faulted (5)
Drive object:
B_INF, VECTOR_G
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:
-
Message class:
Power electronics faulted (5)
Drive object:
B_INF, VECTOR_G
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
Message class:
Auxiliary unit faulted (20)
Drive object:
B_INF, VECTOR_G
Reaction:
NONE
Acknowledge:
NONE
Cause:
Cooling unit: Alarm - flow rate has fallen below the alarm value
Remedy:
- Check the feedback signals and parameter assignment (p0260 ... p0267).
- Check the coolant feed.
