the load is excessively heavy or the acceleration time is excessively short. This
function is always active during acceleration or at constant speed.
Code
C0.27 Stall overcurrent prevention level
The typical behavior of stall overcurrent during acceleration is shown as the fig-
ure below:
Fig. 12-43: Stall overcurrent during acceleration
[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
below:
