Stall overvoltage prevention
This function is used to prevent the frequency converter from overvoltage during
deceleration when the load is excessively heavy or the deceleration time is ex-
cessively short.

With stall overvoltage prevention, the frequency converter detects the DC-bus
voltage and compares it with [C0.26] 'Stall overvoltage prevention level' during
deceleration:
●
[DC-bus voltage] > [C0.26]: The output frequency stops deceasing
●
[DC-bus voltage] < [C0.26]: The output frequency resumes decreasing
The typical behavior of stall overvoltage prevention is shown as the figure below:

If [C0.26] is too low, the deceleration process may fail.
