2.2 List of parameters
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.
Notice: For infeed units, the following applies:
For active powers < 25 % of the rated power, this does not provide any useful information.
Note: Smoothing time constant = 300 ms
The signal is not suitable as a process quantity and may only be used as a display quantity.
Description: Displays the energy values at the output terminals of the power unit.
Index: [0] = Energy balance (sum)
[1] = Energy drawn
[2] = Energy fed back
