• is the controller directly after the supply voltage is switched on.
• the operating system is initialised.
• all device components (power section, communication unit, etc) are identified.
• the parameters are read out of the memory module.
• the settings of the DIP switches are read in and parameters are overwritten.
• it is checked whether the DC-bus voltage is within the tolerance zone and the precharge relay is
closed.
• the inverter is inhibited, i.e., there is no voltage output at the motor terminals.
• the communication via fieldbus or diagnostic interface does not work yet.
• the application is not yet processed.
