Operating state of the inverter

The following table shows the messages of the status for an enabled inverter.

You can toggle between displaying the output frequency, output current, output power, and speed by briefly pressing the <Navigate> key on the keypad.

Message 7-segment display	Message Full text display	Description
H xxx	xxx Hz	Output frequency of the frequency inverter (in Hz) This is displayed when the inverter is enabled.
A xxx	xxx A	Output current of the frequency inverter (in amperes) This is displayed when the inverter is enabled.
P xxx	xxx kW	Output power of the motor (in kW) This is displayed when the inverter is enabled.
L xxx	A padlock appears in the full text display	The parameter is locked for changes. Make sure that: The parameter lock in P2-39 is not activated. The inverter is not enabled. The inverter is supplied with line voltage.
xxxx	xxx rpm	Output speed of the inverter (in min^-1) If the inverter is enabled and a value of > 0 has been set in the parameter P1-10, this is displayed.
C xxx	Scaled value	This is the scaled value, depending on (P2-21/P2-22).
Auto-t	Auto-tuning	An automatic measurement of the motor parameters is being performed. This process can take up to 2 minutes. As soon as the auto-tuning process has completed, the display will revert to STOP.
. . . . . . (flashing dots)	OL (=Over Load)	The output current of the inverter exceeds the current value entered in P1-08. The inverter monitors the extent and the duration of the overload. The inverter triggers fault message "I.t-trP", depending on the overload.
. . (alternately flashing dots)	ML (=Main Loss)	Line phase failure or supply voltage outside specification
FirE	Fire mode	Fire mode/emergency mode activated. The message is displayed alternately with the current operating state.
dELAy.t	Delay-t	Time-delayed reset for i.t-trP, O-I, hO-I, OI-b, see also O-I fault description
	Select Language	List for selecting one of the available languages. To select a language, use the <Navigate> key.
Ho-run	Ho-run	Reference travel started. Wait until the inverter has reached the reference position. After a successful reference travel, "Stop" will appear on the display.
