2
Regeneration avoid function is on only during constant
speed operation (Automatic calculate Acc/Dec speed )
11
Regeneration avoid function is always on. (Manual mode,
Acc/Dec speed is set by 10-49(P.271) and 10-50(P.272))

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 and avoidance 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).
