If output current is lower than the offload detection level (F07.22) and this status
continues for the offload detection time (F07.23) when the offload detection protection is
enabled (F07.21=1) and inverter is in the running mode and not in the DC brake, then
inverter gives an offload protection fault (E26) report and stops as the offload protection
setting (F07.24).

F07.27=0: AVR is disabled.
F07.27=1: AVR is enabled.
AVR function has been effective, if the input voltage is lower than the rated input
voltage, the voltage and the output frequency is greater than the VF curve corresponding
to the frequency, frequency converter will output the maximum voltage in order to make
the most of the motor power output; If the input voltage is higher than the rated input
voltage, the frequency converter can reduce the output voltage, keep the VF proportion.
F07.27=2: AVR is automatic.
AVR function automatically effective (decelerating is invalid): the change of the
frequency converter based on the actual power grid voltage, automatically adjust the
output voltage, and are keeping its rated output voltage

When the stall time is longer than set by F07.28, the drive reports a stall fault;
Stall state, the drive according to F07.29 set value for self-help control. Intensity is
set according to Field application situation, is not the bigger the better.
