2255. Parameter DescriptionEaton Electric General Inverters DF1 Series UMXXXXXXXXE February 2020 www.eaton.com• Using 10-41 to set digital voltage, the setting value of voltage cannot be over the motor rated voltage.• When the setting voltage acceleration time is less than frequency acceleration time or voltage deceleration timeis more thanfrequency deceleration time, voltage stall or current stall may occur during acceleration/ deceleration,which leads to alarm. So it is suggested that 10-42 ＞ 01-06 and 10-43 ＜ 01-07.5.11.14 Regeneration and avoidance function• When the inverter load inertia is larger, PN voltage will increase affected by regenerative power during deceleration orother process, and OV alarm occurs. This function can keep PN voltage on the fixed level and prevent PN level fromincreasing to OV level via adjusting the inverter output frequency and voltage.Parameter Name FactoryValueSettingRange Content10-45P.267Regeneration andavoidance operationselection00 Regeneration avoidance function is invalid.1 Regeneration avoidance function is always valid.(Automatic mode, auto-matic calculation for Acc/Dec speed of action)2Regeneration avoidance function is valid only during a constant speedoperation(Automatic mode, automatic calculation for Acc/Dec speed ofaction)11 Regeneration and avoidance function is effective in running (Manualmode, Acc/Dec speed of action is set by 10-49(P.271) and 10-50(P.272))12 Regeneration and avoidance function only in constant speed (Manualmode, Acc/Dec speed of action is set by 10-49(P.271) and 10-50(P.272))10-46P.268Regeneration andavoidance DC busvoltage level380V 155~400V 220V types760V 310~800V 440V types10-47P.269DC bus voltagedetection sensitivityat deceleration00 Disables regeneration avoidance due to bus voltage change rate.1~5 Set the sensitivity to detect the bus voltage change rate.
