Setting range is related to 10-45 (P.267). If 10-45
(P.267) >10, the setting range is 0~40.00%; If 0-45 (P.267)
<10, the setting range is 0-400.0%.
Adjust the response speed during regeneration avoid
operation. Increasing the set value will improve the response
to the bus voltage changes, but output frequency may be
unstable. If cannot reduced vibration even if 10-49 (P.271) is
reduced, please reduce 10-50 (P.272).

Regeneration avoid function

Regeneration avoid function: In case too many regeneration energy in DC bus trigger inverter OV alarm.
Regeneration avoid function will reduce bus voltage by increasing inverter output frequency when regeneration
voltage exceeds the level, thus avoiding inverter from reporting OV alarm (as shown in the following diagram).
5.11.15 Over excitation deceleration function

Over excitation deceleration function increases the energy consumption of motor by increasing the magnetic flux at
deceleration and stop, which can shorten the deceleration time without braking resistor.

When output current is above the setting level in over
excitation deceleration, over excitation gain will decrease
automatically.
