6 Adjustments6.3.2 Advanced Autotuning Procedure6-226.3.2 Advanced Autotuning ProcedureThe following procedure is used for advanced autotuning.Advanced autotuning is performed from the digital operator (option) or SigmaWin+. The function cannot beperformed from the panel operator.The operating procedure from the digital operator is described here.Refer to theΣ-V Series User’s Manual, Operation of Digital Operator (No.: SIEP S800000 55) for basic keyoperations of the digital operator.(1) Operating ProcedureStep Display after Operation Keys Operation1Press the Key to view the main menu for theutility function.Use the or Key to move through the list,select Fn201.2 Press the Key to display the initial setting screenfor Fn201(Advanced Autotuning).3 Press the , , or Key and set the items insteps 3-1 to 3-4.3-1Calculating Moment of InertiaSelect the mode to be used.Usually, set Jcalc to ON.Jcalc = ON: Moment of inertia calculated [Factory setting]Jcalc = OFF: Moment of inertia not calculatedNote:If the moment of inertia ratio is already known from the machine specifications, set the value in Pn103and set Jcalc to OFF.3-2Mode SelectionSelect the mode.Mode = 1: Makes adjustments considering response characteristics and stability (Standard level).Mode = 2: Makes adjustments for positioning [Factory setting].Mode = 3: Makes adjustments for positioning, giving priority to overshooting suppression.3-3Type SelectionSelect the type according to the machine element to be driven. If there is noise or the gain does not increase, bet-ter results may be obtained by changing the rigidity type.Type = 1: For belt drive mechanismsType = 2: For ball screw drive mechanisms [Factory setting]Type = 3: For rigid systems in which the servomotor is directly coupled to the machine (without gear or othertransmissions)3-4STROKE (Travel Distance) SettingTravel distance setting range:The travel distance setting range is from -99990000 to +99990000 [reference unit]. Specify the STROKE(travel distance) in increments of 1000 reference units. The negative (-) direction is for reverse rotation,and the positive (+) direction is for forward rotation.Initial value:About 3 rotationsNotes:• Set the number of motor rotations to at least 0.5; otherwise, "Error" will be displayed and the travel distancecannot be set.• To calculate the moment of inertia and ensure precise tuning, it is recommended to set the number of motorrotations to around 3.㧮㧮 ޓ̆ 㧲㨁㧺㧯㨀㧵㧻㧺̆㧲㨚㧞㧜㧜㧦㨀㨡㨚㨑㧸㨢㨘ޓ㧿㨑㨠㧲㨚㧞㧜㧝㧦㧭㧭㨀㧲㨚㧞㧜㧞㧦㧾㨑㨒㧭㧭㨀㧲㨚㧞㧜㧟㧦㧻㨚㨑㧼㨞㨙㨀㨡㨚㧮㧮 㧭㨐㨢㨍㨚㨏㨑㧭㨀ޓ㨐ޓ㧶㨏㨍㨘㨏㧩㧻㧺ޓ㧹 㨛 㨐 㨑㧩㧞ޓ㨀㨥㨜㨑㧩㧞ޓ㧿㨠㨞㨛㨗㨑㧩㧗㧜㧜㧤㧜㧜㧜㧜㧜㧔㧜㧜㧜㧟㧚㧜㧕㨞㨑㨢ޓޓޓޓޓޓStatus Display㧮㧮 㧭㨐㨢㨍㨚㨏㨑㧭㨀ޓ㨐ޓ㧶㨏㨍㨘㨏㧩㧻㧺ޓ㧹 㨛 㨐 㨑㧩㧞ޓ㨀㨥㨜㨑㧩㧞ޓ㧿㨠㨞㨛㨗㨑㧩㧗㧜㧜㧤㧜㧜㧜㧜㧜㧔㧜㧜㧜㧟㧚㧜㧕㨞㨑㨢ޓޓޓޓޓޓ
