Press Regeneration Prevention
Press regeneration prevention is used during press operations to prevent braking during
the regeneration process. When motor regeneration occurs during a press operation, the
motor operating speed automatically increases to avoid the regeneration zone.

Description
Ad.74 RegenAvd Sel
Frequent regeneration voltage from a press load during constant
motor speed operation may force excessive work on the brake unit
which may damage or shorten the brake life. To prevent this
situation, set Ad.74 (RegenAvd Sel) to 1 (Yes) to control DC link
voltage and disable the brake unit operation.
Ad.75 RegenAvd
Level
Set the DC Link voltage level to activate Regen Avoidance.
Ad.76 CompFreq

Set a frequency limit above operating frequency during Regen
Avoidance.
