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
controller 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 drive
controller and the drive controller 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.
