3.3 Communication with the inverter

The Process Data window (Figure 3-8) displays information about the inverter. For the sake of better clarity, the window is divided into a number of panes. You can specify the number of panes and their content in a configuration file. In the default configuration, the content of the individual panes is as follows:

Device Information

The device information box displays the software version of the CU4 control unit. The date of software creation (day, month and year) is specified. In addition, the box also shows the performance class, MLFB, operating hours and status of the inverter (sequence control status).

SINVERT-Settings

You can adjust the inverter settings in this screen, e.g. normal operation, standard and expert mode (depending on access authorization).

The setting Normal Operation permits access only to monitoring functions, but inhibits changes to parameter values.

The setting Standard permits parameter values to be changed.

The setting Experts permits special, extensive changes to parameter values.

Various functions can be selected for the settings. When you select the Return function, values cannot be changed. This means that a pure monitoring function is assigned to the setting. The function Initial Program Loading essentially initializes the inverter and is generally only used to restore the Siemens factory settings. The function Commissioning permits parameters to be changed during the commissioning process.
