This function is used to prevent the frequency converter from overcurrent when
the load is excessively heavy or the acceleration time is excessively short. This
function is always active during acceleration or at constant speed.

The typical behavior of stall overcurrent during acceleration is shown as the fig-
ure below:

●
[Output current] > [C0.27]
The output frequency stops increasing.
●
[Output current] < [C0.27]
The output frequency resumes increasing to the setting frequency with de-
fined acceleration time.
The typical behavior of stall overcurrent at constant speed is shown as the figure
