Appendix04/07 AWB8230-1541GBSpecifying the control modeX With the buttons in the Gerätesteuerung – <strong>Moeller</strong> DF51 youcan select the control mode PC or <strong>Frequency</strong> inverter.Figure 201:Selecting control mode PC or <strong>Frequency</strong> inverter• OfflineIn offline mode, the frequency inverter’s parameters are notchanged directly. Device control is not enabled in this case.The parameters can be read out from the frequency inverter withUpload, edited at the PC and saved to the frequency inverter againwith Download.• OnlineIn online operation, the PC is connected directly with the frequencyinverter. The device control is enabled.The frequency inverter’s parameters can be changed directly.• MonitoringIn monitoring mode, the frequency inverter is only monitored.Device control is not enabled in this case.The parameters can be read out with Upload and the trend displayand the fault memory can be viewed. The parameters can not beedited directly.A prepared parameter set can be loaded to the frequency inverterwith Download without establishing an online connection.Depending on the value of PNU A001 (control signal source) andA002 (reference source) reference values and control signals canbe defined. Parameters A001 and A002 themselves can not bechanged.• UploadThe PC is always regarded as the higher-level device. “Upload”therefore always refers to a transfer of data from the frequencyinverter to the PC.• DownloadThe PC is always regarded as the higher-level device. “Download”therefore always refers to a transfer of data from the PC to thefrequency inverter.• Speichern (EEPROM)The data transfer to the frequency inverter takes place in operatingmodes Online, Monitoring and Download. The data is written tovolatile (non-retentive) memory, so that all transferred data is lostwhen the power supply is switched off. To save the data to thefrequency inverter, click the Speichern (EEPROM) button.214
