Useful to provide warning prior to the drive taking action that is selected byP410 [Motor OL Actn]. This alarm level is different than , and independent of, the“Alarm” action selected by P410 [Motor OL Actn].Units: %Default: 0.00Min/Max: 0.00 / 100.00RW RealPROTECTIONMotor Overload413 Mtr OL FactorMotor Overload FactorSets the minimum level of current (in percent or P26 [Motor NP Amps]) thatcauses the motor overload counter to increment. Current levels below this valuewill decrement the overload counter. For example, a service factor of 1.15 impliescontinuous operation up to 115% of nameplate motor current.414 Mtr OL HertzMotor Overload HertzSelects the output frequency below which the motor operating current is derated(more sensitive) to account for the reduced self-cooling capability of typicalmotors, operating at slower speeds. For motors with extra low speed coolingcapacity (e.g. 10:1 or blower cooled), reduce this setting to take full advantage ofthe motor being used.Default: 1.00Min/Max: 0.20 / 2.00Units: HzDefault: 20.00Min/Max: 0.00 / 4096RW RealRW Real415 Mtr OL Reset LvlMotor Overload Reset LevelSets the level that resets a motor overload condition, and allows a fault (ifselected as the motor overload action) to be manually reset.416 MtrOL Reset TimeMotor Overload Reset TimeDisplays the time it will take to restart the drive after a motor overload fault hasoccurred and the value in P418 [Mtr OL Counts] is less than the P415 [Mtr OLReset Lvl].418 Mtr OL CountsMotor Overload CountsAccumulated percentage of motor overload. Continuously operating the motorover 100% of the motor overload setting will increase this value to 100% andcause the action selected in P410 [Motor OL Actn] to be taken.Units: %Default: 0.00Min/Max: 0.00 / 100.00RW RealUnits: SecsDefault: 0.00Min/Max: –/+99999.00RW RealUnits: %Default: 0.00Min/Max: 0.0 / 100.00ROReal419 Mtr OL Trip TimeMotor Overload Trip timeDisplays the inverse of the motor overload time, equal to the number of secondsbefore P418 [Mtr OL Counts] reaches 100%, and the motor overload action istaken.Units: SecsDefault: 99999Min/Max: 0 / 99999RO32-bitIntegerPowerFlex 750-Series User Manual – Publication 750-UM001C-EN-P – September 2009
