NOTES!
The factory setting is at maximum (Link regulation is
deactivated). To activate this regulation, we recommend to set
P151 according table 6.8.
If even after this setting the inverter is still disabled due to
overvoltage (E01) during the load acceleration, increase the value
of the Parameter P152 gradually, or increase the deceleration
ramp time (P101 and/or P103). The inverter will not decelerate,
if the supply line is permanently under overvoltage Ud > P151).
In this case reduce the line voltage or increment P151.

For large motors it’s recommended the use of the ramp holding
function.
