Code Description
ADV-74
RegenAvd Sel
Frequent regeneration voltage from a press load during a constant speed
motor operation may force excessive stress on the brake unit, which may
damage or shorten brake life. To prevent this, select ADV-74 (RegenAvd Sel) to
control DC link voltage and disable the brake unit operation.
ADV-75
RegenAvd Level Set brake operation prevention level voltage when the DC link voltage goes up
due to regeneration.
ADV-76
CompFreq Limit Set an alternative frequency width that can replace actual operation frequency
during regeneration prevention.

Note
Press regeneration prevention does not operate during accelerations or decelerations; it only operates
during constant speed motor operation. When regeneration prevention is activated, output frequency
