5.4.12 ADV-74 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, motor operation
speed automatically increases to avoid the regeneration zone.

Description
ADV-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 ADV-74 (RegenAvd Sel) to control DC bus voltage and disable
the brake unit operation.

Set the DC bus voltage level to activate Regen Avoidance.

Set the P gain and I gain in the DC bus voltage suppressor PI controller while in Regen
Avoidance.
Note
Press regeneration prevention only operates during constant speed motor operation. It does
not operate during accelerations or decelerations. When regeneration prevention is activated,
output frequency may change within the range set at ADV-76 (CompFreq Limit).
