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.
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.
