The DC link voltage regulation (ramp holding) avoids in-
verter disable due to overvoltage trips (E01) during
deceleration of loads with high inertia or short
deceleration times.
It acts in order to increase the deceleration time
(according to load - inertia), thus avoiding the E01
activation.

By this function an optimized deceleration time
(minimum) is achieved for the driven load.
This function is useful in applications with medium inertia
that require short deceleration times.
In case of overvoltage trip during the decelearation, you
must reduce gradually the value of P151 or increase the
time of the deceleration ramp (P101 and/or P103).
