■ For Enable acceleration ("Overvoltage suppression enable [b130]" = 02)
Enable acceleration performs acceleration operation according to "Overvoltage suppression
active time [b132]" when the P-N voltage exceeds the overvoltage suppression active level
during deceleration. Normal deceleration is then resumed when the P-N falls to or below the
overvoltage suppression active level.
If the "Overvoltage suppression active time [b132]" is shortened, an increase in the output
frequency due to acceleration is greater than that of the deceleration, and as a result, the motor
may not be able to stop. In such a case, increase the "Overvoltage suppression active level
[b131]".
