4 Faults and alarms
4.2 List of faults and alarms
SINAMICS G120D
860
List Manual (LH14), 01/2016, A5E33842313
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.
See also: r0037 (Power unit temperatures)
Remedy:
Not necessary.
The alarm disappears automatically once the limit value is undershot.
Note:
If the alarm does not disappear automatically and the temperature continues to rise, this can result in fault F30024.

A05065 (F, N)
Voltage measured values not plausible
Message class:
Power electronics faulted (5)
Reaction:
NONE
Acknowledge:
NONE
Cause:
The voltage measurement does not supply any plausible values and is not used.
Alarm value (r2124, interpret bitwise binary):
Bit 1: Phase U
Bit 2: Phase V
Bit 3: Phase W
Remedy:
The following parameterization must be made in order to de-activate the alarm:
- De-activate voltage measurement (p0247.0 = 0).
- De-activate flying restart with voltage measurement (p0247.5 = 0) and de-activate fast flying restart (p1780.11 = 0).
F06310 (A)
Supply voltage (p0210) incorrectly parameterized
Message class:
Network fault (2)
Reaction:
NONE (OFF1, OFF2)
Acknowledge:
IMMEDIATELY (POWER ON)
Cause:
The measured DC voltage lies outside the tolerance range after precharging has been completed.
Permissible range:
1.16 * p0210 < r0070 < 1.6 * p0210
Note:
The fault can only be acknowledged when the drive is switched off.
