SINAMICS S List Manual (LH1), 07/2007
64: Overvoltage in the positive partial DC link (VdcN)
96: Overvoltage in both partial -DC links
Remedy:
- increase the ramp-down time.
- activate the DC link voltage controller.
- use a brake resistor or Active Line Module.
- increase the current limit of the infeed or use a larger module (for the Active Line Module).
- check the line supply voltage.
- check and correct the phase assignment at the VSM and at the power unit.

F30003
Power unit: DC link voltage, undervoltage
Drive object:
All objects
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
Cause:
The power unit has detected an undervoltage condition in the DC link.
- line supply failure
- line supply voltage below the permissible value.
- line supply infeed failed or faulted.
Note:
The monitoring threshold for the DC link undervoltage is the minimum of the following values:
- 85% of the unit supply voltage (p0210).
- lowest permissible lower DC link voltage of the power units (descriptive data).
Remedy:
- check the line supply voltage
- check the line supply infeed and if necessary observe the fault messages of the line supply infeed.
Note:
The ready signal of the infeed r0863 must be connected to the associated inputs p0864 of the drives.

F30004
Power unit: Overtemperature heatsink AC inverter
Drive object:
All objects
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
Cause:
The temperature of the power unit heatsink has exceeded the permissible limit value.
- insufficient cooling, fan failure.
- overload
- ambient temperature too high.
- pulse frequency too high.
Fault value (r0949):
Temperature [1 bit = 0.01 °C].
Remedy:
- check whether the fan is running.
- check the fan elements
- check whether the ambient temperature is in the permissible range.
- check the motor load.
- reduce the pulse frequency if this is higher than the rated pulse frequency.
Notice:
This fault can only be acknowledged after this alarm threshold for alarm A05000 has been fallen below.

F30005
Power unit: Overload I2t
Drive object:
All objects
Reaction:
OFF2
Acknowledge:
IMMEDIATELY
Cause:
The power unit was overloaded (r0036 = 100 %).
- the permissible rated power unit current was exceeded for an inadmissibly long time.
- the permissible load duty cycle was not maintained.
Fault value (r0949, interpret decimal):
I2t [100 % = 16384].
