H75: DB resistor ED limit setting0 No limitCautionTake caution when DB resistor is used over its Watt rating. Fire mayresult from resistor overheat. When resistor having heat detection sensoris used, sensor output can be used as external trip signal in multifunctioninput.1 ED is limited as the setting in H 76. H76: set the resistor operating rate(%ED) in one sequence of operation. Continuous usagereate is Max 15 sec and usage signal is not issued over 15 sec.Ex 1)T _ decH 76 =× 100[%]T _ acc + T _ steady + T _ dec + T _ stopWhere,T_acc: Acceleration time to reach a setting freq.T_steady: Time for constant speed operation at setting freq.T_dec: Time to decelerate to lower freq. than that in constant speedor time to stop from freq. in constant speed.T_stop: waiting time at a stop before operation is resumed.Freq.T_acc T_steady T_dec T_stopT _ decH 76 =× 100[%]Ex 2) T _ dec + T _ steady1+ T _ acc + T _ steady2Freq.T_decT_accT_steady1T_steady210-8
