2.2 List of parameters
Description:
Displays the power unit overload determined using the I2t calculation.
A current reference value is defined for the I2t monitoring of the power unit. It represents the current that can be
conducted by the power unit without any influence of the switching losses (e.g. the continuously permissible current
of the capacitors, inductances, busbars, etc.).
If the I2t reference current of the power unit is not exceeded, then an overload (0 %) is not displayed.
In the other case, the degree of thermal overload is calculated, whereby 100% results in a trip.
Dependency:
Refer to: p0290, p0294
Refer to: F30005
Description:
Display and connector output for the temperature in the power unit.
Index:
[0] = Inverter maximum value
[1] = Depletion layer maximum value
[2] = Rectifier maximum value
[3] = Air intake
[4] = Interior of power unit
[5] = Inverter 1
[6] = Inverter 2
[7...10] = Reserved
[11] = Rectifier 1
[12] = Reserved
[13] = Depletion layer 1
[14] = Depletion layer 2
[15] = Depletion layer 3
[16] = Depletion layer 4
[17] = Depletion layer 5
[18] = Depletion layer 6
[19] = Reserved
Notice:
Only for internal Siemens troubleshooting.
Note:
The value of -200 indicates that there is no measuring signal.
r0037[0]: Maximum value of the inverter temperatures (r0037[5...10]).
r0037[1]: Maximum value of the depletion layer temperatures (r0037[13...18]).
r0037[2]: Maximum value of the rectifier temperatures (r0037[11...12]).
The maximum value is the temperature of the hottest inverter, depletion layer, or rectifier.
r0037[2, 3, 6, 11, 14...18] is only relevant for chassis power units.
In the case of a fault, the particular shutdown threshold depends on the power unit, and cannot be read out.
Description:
Displays the smoothed actual power factor. This refers to the electrical power of the basic fundamental signals at the
converter output terminals.
