! The fault code is used for the communication read fault type: when the communication reads
the registers r25.00, r26.00, r26.08, r26.16, the register contents of the reply are fault coded.

6.2 Warning type

The warning is used to remind and inform the user of the current state of the inverter. When the warning
occurs, the keypad will display a warning message, and the warning will automatically reset when the
warning is cleared. Some warnings require the user to check the cause before running the drive, and
some do not care. Warning As an instant reminder, the drive does not store the corresponding
information.
Bit 12 of r27.10 indicates whether there is a warning message currently.
