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.

feedback>P40.37 setting
value and P40.38 not zero
1: The signal of user-defined fault
1 is
Er.Ud1 input via DI.
2:The signal of user-defined fault 1
is
input via virtual I/O.
1: The signal of user-defined fault
2 is
Er.Ud2 input via DI.
2:The signal of user-defined fault 2
is
input via virtual I/O.
Display
PoFF 1: The DC link voltage is insufficient
and cannot be started normally.
1: The parameter settings are wrong,
such as:
A.PARA
The torque mode is set in the VF
control mode.
1. The system is in a sleep state, and
SLEEP
the system will automatically start
when hibernation is over.
