4.2.5 ReadyToSwitchOn
The inverter is in this device status directly after the initialisation has been completed!
• The bus systems are running and the terminals and encoders are evaluated.
• The monitoring functions are active.
• The inverter can be parameterised.
• The application is basically executable.

 Note!
• The "ReadyToSwitchOn" state is not only activated after the mains connection, but
also after the deactivation of "Trouble
", "Fault" or "SafeTorqueOff".
•If C00142
activates the autostart option "Inhibit at power-on" (Lenze setting), explicit
deactivation of the controller inhibit after mains connection is always required for the
inverter to change from the "ReadyToSwitchOn" status to the "SwitchedOn
" status.
• If only the 24V voltage supply is available during the mains connection, the error
message "LU: Undervoltage in the DC bus
" is entered into the logbook of the inverter
and the inverter remains in the "ReadyToSwitchOn" status.
 Danger!
If the "Inhibit at power-on" auto-start option has been deactivated in C00142, the
"ReadyToSwitchOn status switches directly to the "SwitchedOn
" status after mains
connection.
