The manual is intended to be used as a supplement to the 590D user manual HA387240 It is important that the user be familiar with setting and configuring the 590D drive, and in particular the following topics Using the mmi Adjusting set-up parameters Monitor diagnostic parameters Change configuration connections using tags These topics are thoroughly covered in the 590D user manual The special winder blocks use the flexibletag connection scheme within the 590d to allow a variety of different centre winder configurations. This manual outlines typical examples of centre winder configurations These may be customised to suit individual requirements SOFTWARE COMPATIBILITY 款房互 This manual is written to be compatible with the following software 590D drive Issue 3.2 software ConfigEd Lite A graphical programming tool for the 590D drive is available, called ConfigEd Lite. This tool allows block diagrams to be easily constructed in a windows environment Config Ed Lite template configuration files are available for the 590D intemal block diagrams shown in this manual The filenames are:- Dancer Controlled Centre Winder SPW DC. 590 Load cell Controlled Centre Winder SPW LC. 5 90 Installing a new block diagram from the template filename shown above is covered in the ConfigEd Lite user Manual con作 Ed lite Issue 1.00 AP PLICATION ypical examples of closed loop winders are descrbed which include: Load cell feedbacl Dancer feedback Simple set-up instructions are given The closed loop centre winders described in this manual use the 590d drive in speed contol. Here, speed feedback from the motor must ded usingan analog or digital tachometer. The use of armature voltage feedback is not recommended que to the low accuracy Chapter 2 Special block description Chapter 2 Special block description This section describes each of the special blocks irfdetdif.

The filter ramp must be set to a long ramp rate. The filter has fa es for.

The diameter filter prevents the diameter from changing quickly in the case of web break SiTuatIonS The diameter output is clamped at the minimum diameter constant value 作1 Chapter 2 Special block description TAPER CALC BLOCK B&A计 l流台 This special block performs processes the tension and taper set points to process a composite tension demand value. The tension demand value is normally used to set 1)The tension setpoint for load cell feedback systems 2) The extemal dancer force for dancer controlled systems. This is normally performed via an E/P converter This block is directly connected to the diameter and minimum diameter parameters as described above a tension demand trim input is provided, although this is not normally used in this application Two outputs are provided for 1)Total Tension demand 2)Tapered Demand. This is the tapered output, before the Tension Trim is added The Taper Calculator block diagram is shown below spt.[4391 100 Diamete Tapered Demand 452] Min diameter Taper Function Total Tension demand Toper [438 44] Tension Tri 'Permanently linked 440 to diameter calc A fixed hyperbolic taper characteristic is supplied with this block which has gives the following tension characterstics Tension orque 100% Tape 100%Tp 0%Ta 00‰uper 100%o Ccer Diameter 100 100% Diameter D ameter Diameter Diameter If the Taper input is O% this gives a constant tension characteristic with diameter If the taper input is between 0 and 100%, this gives tension falling with increasing diameter. This Is sometimes known as negative taper If the taper input is between 0 and-100%, this gives tension rising with increasing diameter. This Is sometimes known as positive taper. All taper characteristics start at the tension setpoint, at minimum diameter. The following equation shows the actual taper calculation. Chapter 2 Special block description PID BLOCK The Pid block is designed to allow closed loop control of a feedback variable compared to a setpoint variable. The three control terms(PiD)are adjustable to optimise control response Integral control is used to give zero steady state error The following block diagram shows the PID block, which is found in the SEtuP PARAMETERS /SPECIAI, BLOCKS menu of the drive Enable[408 Integral Defea 4C From gain Profiler Ratio 1 Divider 1 412][412 O/P Scal rm)2407] Pos iimit [410 Reset [402] [405 PID Output 1417 Input 2 [401 410 Neg Limit Ratio 2 Divider 2 406 412]412 403 PID Error [415] F The Pid has two inputs which are scaled with independent parameters of RatIO and DIVider The two scaled inputs are subtracted to form an error value and the resultant three term control (PD)operates on this error The two scaled inputs are usually assigned to setpoint and feedback of the closed loop control system The following diagram shows the classical PID characteristic Gain y Prop Lod eg Derivative filter The three main pid variables are described below Chapter z special block description Proportional gain The PID error is multiplied by the Proportional gain to produce an output The proportional gain is used to adjust the basic response of the closed loop control system. Note that this value does not affect any of the other Pid parameters Typical responses of a Pid controlled system are shown below. The ideal response is the critically damped characteristic Underdamped Setpoint value Overdamped Critically damped Integral This is used to give zero steady state error between the setpoint and feedback values of the PiD This ensures for example, that the steady state position of a dancer in a controlled drive section, will aways be equal to the setpoint If the integral is set to a small value, this will cause an under damped or unstable control system Derivative This is used to correct for certain types of control loop instability, and therefore improve response. It is sometimes used when heavy or large inertia rolls are being controlled The derivative term has an associated filter, to suppress high frequency signals Proportional Gain profiler When the PiD is used for a centre winder application, the resultant control response is affected by the change in load inertia due to the changing roll diameter. If the diameter change is large, the resultant change in inertia may be such that the winder is unstable or under damped at one of the extreme ends of the diameter range This is compensated using a diameter gain profiler within the Pid block. A block diagran of this profiler is shown below
