controller,and does not need to feedback the current position or external tension signal,andeven does not need to use speed feedback PG to realize constant tension control.However,inthe tension control with a high requirement,speed feedback PG should be used.Speed control mode:Realize precise speed PID regulation through extemal line speedreference and the feedback signals that represent the current position or tension,so as to makethe position signal or tension feedback signal in preset balance position to realize constanttension control.In this working mode,the inverter does not need external tension controller andspeed feedback PG,but needs the external signal that represents the current position ortension to realize constant tension control.Typical Reeling-in Tension ControlLeadingReeling-inFigure 1 Constant tension control can be realized in torque control modeLeading Position or tension feedbackReeling-inFigure 2 Constant tension control can be realized in speed control modeIntroduction to Tension Control Solution◆Torque solutionTorque control mode means the inverter controls motor output torque instead offrequency,and the output frequency changes automatically with the speed change.1)Simple tension control modeIn this mode,there is no tension feedback signal,no internal automatic reeldiameter calculation,with the increase of reel diameter,the output torque of reel-in axisis bigger and bigger,due to the adjustment of tension coefficient,and the output torqueof reel-in axis bees bigger also to realize the constant tension control.2)Constant tension control modeIn this mode,there is no tension feedback signal,no internal automatic reeldiameter calculation,with the increase of reel diameter,the output torque of reel-in axischanges according to the formula F=T/R(wherein,F:tension of material;T:torque ofreel-in axis;R:radius of reel),so,to maintain constant F,with the increase of reeldiameter,T=F*R also increases to realize the constant tension control.3)Torque PID control modeTorque PID control mode needs tension feedback signal,the inverter automaticallyadjusts the output torque according to the feedback tension so as to realize theconstant tension control.Functional module related to torque mode1)Tension setting part Used to set the tension,user can set according to the materialsand process requirement for reeling,and the tension taper can be used to decreasethe tension with the increase of the reel diameter so as to improve the reel shape;2)Reel diameter calculation part:Used for calculating or obtaining reel diameter andselecting calculating method according to different applications:Line speed mode,analog value mode and pulse mode;3)Torque pensation part:Some part of the output torque is used to overe therotating inertia of the reeling-in(out)rod during acceleration or deceleration process,torque pensation can be made for the inertia according to the acceleration ordeceleration rate through proper parameter settings automatically.so as to keep thestable tension during acceleration or deceleration process.The pensation forfriction can overe the affect of the system friction to the tension.4)Automatic reel change part:Perform automatic reel change in running process,need to set the pre-drive function in torque mode.◆Speed SolutionIn speed mode,inverter can work in following modes:Vector control without speed PGfeedback 1,vector control without speed PG feedback 2 and vector control with speed PGfeedback 2.1)Speed PID control modeSpeed PID control needs tension or position feedback signals to fomm a close loopregulation,and the inverter automatically regulate the output frequency according to thefeedback signal to control the tension or position to achieve the preset value.2)Constant line speed control modeFor some applications that require stable running but do not need fast adjustmentof line speed,use constant line speed control mode to perform constant line speedcontrol without PID regulator,more stable than mon close loop control.Functional Module Related to Speed Mode1)PID part:The target value channel and feedback signal value of PID are set by H1group of parameters,and the PID parameters are mainly set by P8 group,and thesecond group of PID parameters in H1 group can provide assistance to realize thelinear switching between two sets of PID parameters and realize better result in thewhole process.2)Line speed input part:This part is important,and there are two functions:one is tocalculate the matching frequency of the inverter through line speed and another is tocalculate the reel diameter through line speed.3)Reel diameter calculation part:Used for calculating or obtaining reel diameter andselecting calculating method according to different applications:Line speed mode,analog value mode and pulse mode;4)Automatic reel change part:Perform automatic reel change in running process,need to set the pre-drive function in torque mode.Setting of Tension Control FunctionsFunction CodesFunctions in Tension ControlH0.00toH0.29Set reeling mode,reference tension and tension taperH0.30toH1.06Line speed setting,reel diameter
