For example: To stop the inverter according to the stop mode (F04.19) after the
E08
and
E13
failure, you only need to set the 1
st
bit corresponding to
E08
and the 3
rd
bit
corresponding to
E13
to 1. That is, F07.19=xxx x1x1x.

When the off-load protection is valid (F07.21=1), the inverter will be in the running
status without DC braking, and the output current is below the off-load detection level
(F07.22) and maintained for the off-load detection time (F07.23), the inverter will be in the
off-load status. Specific processing depends on F07.24.

○
F07.27=0: invalid
The automatic voltage regulation (AVR) function is invalid.
F07.27=1: valid
The AVR function is continuously valid. If the input voltage is lower than the rated
input voltage, and the output frequency is greater than the corresponding frequency on the
VF curve, the inverter will output the maximum voltage to maximize the power output of
the motor. If the input voltage is higher than the rated input voltage, the output voltage of
the inverter will decrease, and the VF ratio will remain unchanged.
F07.27=2: automatic
The AVR function is valid automatically (invalid during deceleration): the inverter will
automatically adjust the output voltage according to changes in the actual grid voltage, to
keep it at the rated output voltage.
