5.33 Press Regeneration Prevention
Press regeneration prevention is used during press operations to prevent braking during the
regeneration process. If motor regeneration occurs during a press operation, motor operation speed
automatically goes up to avoid the regeneration zone.

Press Regeneration Prevention Setting Details
Ad.74 RegenAvd Sel
Frequent regeneration voltage from a press load during constant speed
motor operation may force excessive work on the brake unit which may
damage or shorten the brake life. To prevent this situation, select Ad.74
(RegenAvd Sel) to control DC link voltage and disable the brake unit
Ad.75 RegenAvd Level
Set brake operation prevention level voltage when the DC link voltage goes
up due to regeneration.
