A30057
Power unit: Line asymmetry
Reaction:
NONE
Acknowledge:
NONE
Cause:
Frequencies have been detected on the DC link voltage that would suggest line asymmetry or failure of a line phase.
It is also possible that a motor phase has failed.
Fault F30011 is output if the alarm is present and at the latest after 5 minutes.
The precise duration depends on the power unit type and the particular frequencies. For booksize and chassis power units,
the duration also depends on how long the alarm has been active.
Alarm value (r2124, interpret decimal):
Only for internal Siemens troubleshooting.
Remedy:
- check the line phase connection.
- check the motor feeder cable connections.
If there is no phase failure of the line or motor, then line asymmetry is involved.
- reduce the power in order to avoid fault F30011.
F30059
Power unit: Internal fan faulty
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
Cause:
The internal power unit fan has failed and is possibly defective.
Remedy:
Check the internal fan and replace if necessary.
A30065 (F, N) Voltage measured values not plausible
Reaction:
NONE
Acknowledge:
NONE
Cause:
The voltage measurement is not supplying any plausible values
Alarm value (r2124, interpret bitwise binary):
Bit 1: Phase U.
Bit 2: Phase V.
Bit 3: Phase W.
Remedy:
- Deactivate voltage measurement (p0247.0 = 0).
- Deactivate flying restart with voltage measurement (p0247.5 = 0) and deactivate fast flying restart (p1780.11 = 0).
F30068
Power unit: undertemperature inverter heat sink
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
Cause:
The actual inverter heat sink temperature is below the permissible minimum value.
Possible causes:
- the power unit is being operated at an ambient temperature that lies below the permissible range.
- the temperature sensor evaluation is defective.
Fault value (r0949, interpret decimal): inverter heat sink temperature [0.1 °C].
Remedy:
- ensure that higher ambient temperatures prevail.
- replace the power unit.
F30071
No new actual values received from the Power Module
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
Cause:
More than one actual value telegram from the power unit module has failed.
Remedy:
Check the interface (adjustment and locking) to the power unit module.
