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
.

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.
