AKD 5000 Parameters — References and limits201 Output frequency low limit (FMIN )(OUT FREQ LOW LIM)Value:0.0 - f MAX ✭ 30.0 HzFunction:In this parameter, a minimum motor frequency limitcan be selected that corresponds to the minimumfrequency at which the motor is to run.The minimum frequency can never be higher thanthe maximum frequency, fMAX .If Both directions has been selected in parameter 200,the minimum frequency is of no significance.Description of choice:A value from 0.0 Hz to the max. frequency selectedin parameter 202 (f MAX ) can be chosen.202 Output frequency high limit (FMAX)(OUT FREQ HI LIM)Value:fMIN - 132 ✭ 60 HzFunction:In this parameter, a maximum motor frequency can beselected that corresponds to the highest frequency atwhich the motor is to run. The factory setting is 60Hz for AKD 5001-5062 380-500 V, AKD 5001-5062550-600 V and 5001-5027 200-240 V.See also parameter 205.NB!:The output frequency of the frequency convertercan never assume a value higher than 1/10of the switching frequency.204 Minimum reference(MIN. REFERENCE)Value:-100,000.000 - Ref MAX ✭ 30.0 HzDepends on parameter 100.Function:The Minimum reference gives the minimum valuethat can be assumed by the sum of all references.Minimum reference is always active in Processcontrol, closed loop (parameter 100).Description of choice:Set the desired value.The unit follows the choice of configurationin parameter 100.Speed control, open loop: HzSpeed control, closed loop: rpmTorque control, open loop: NmTorque control, speed feedback: NmProcess control, closed loop: Process units(par. 416)Special motor characteristics, activated in parameter101, use the unit selected in parameter 100.205 Maximum reference(MAX. REFERENCE)Value:Ref MIN - 100,000.000 ✭ 60.0 HzFunction:The Maximum reference gives the highest value thatcan be assumed by the sum of all references. Ifclosed loop has been selected in parameter 100,the maximum reference cannot be set higher thanthe maximum feedback (parameter 415).Description of choice:Set the desired value.The unit follows the choice of configurationin parameter 100.Speed control, open loop: HzSpeed control, closed loop: rpmTorque control, open loop: NmTorque control, speed feedback: NmProcess control, closed loop: Process units(par. 416)Special motor characteristics, activated in parameter101, use the unit selected in parameter 100.207 Ramp-up time 1(RAMP UP TIME 1)Value:0.05 - 3600 sec. ✭ 0.7 secFunction:The ramp-up time is the acceleration time from 0 Hzto the rated motor frequency fM,N (parameter 104) or✭ = factory setting.
