4 Faults and alarms
4.2 List of faults and alarms
SINAMICS G130/G150
1518 List Manual (LH2), 07/2016, A5E03263479A
Reaction upon A: NONE
Acknowl. upon A: NONE
A05000 (N) Power unit: Overtemperature heat sink AC inverter
Message value: -
Message class: Power electronics faulted (5)
Drive object: B_INF, VECTOR_G
Component: Power Module Propagation: GLOBAL
Reaction: NONE
Acknowledge: NONE
Cause: The alarm threshold for overtemperature at the inverter heat sink has been reached. The response is set using
p0290.
If the temperature of the heat sink increases by an additional 5 K, then fault F30004 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?
Reaction upon N: NONE
Acknowl. upon N: NONE
A05001 (N) Power unit: Overtemperature depletion layer chip
Message value: -
Message class: Power electronics faulted (5)
Drive object: VECTOR_G
Component: Power Module Propagation: GLOBAL
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 depletion layer temperature increases by an additional 15 K, then fault F30025 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 cooling failed?
- pulse frequency too high?
Note:
If the alarm occurs after reducing the current controller sampling time (p0115[0]) during the motor data identification
(standstill measurement), then it is recommended that this is initially performed using the standard sampling time and
then the sampling time should be subsequently changed over.

Reaction upon N: NONE
Acknowl. upon N: NONE
A05001 (N) Power unit: Overtemperature depletion layer chip
Message value: -
Message class: Power electronics faulted (5)
Drive object: B_INF
Component: Power Module Propagation: GLOBAL
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 depletion layer temperature increases by an additional 15 K, then fault F30025 is triggered.
