Software of Dorna Servos on Winding Machine
Abstract: This paper describes software of Dorna EPS sequence servo technique on winding device based mostly on evaluation of working basic principle of winding device. Options of critical of parameters of servo drives are also offered.
one. Introduction
Winding machine is essential processing equipment widely utilised in electrical and digital business. It is to use enameled copper wire to wind inductors. It is 1 piece of mechanical gadget necessitating higher management precisions of pace and accuracy. The control program is essential to supply quite specific & sleek line pace and adaptable commutation ability.  winding equipment are widely used for producing annular main voltage regulators, transformers, present mutual inductors and so on.
There is a variety of winding equipment like parallel winding equipment, annular winding devices, stator/rotor winding equipment, textile winding devices, as effectively as voice coil winding machines.
2. Composition of a winding equipment
Upper personal computer is normally SCM or PLC with text exhibit for automated manage. Use angle and revolution variety to established the magnetic ring winding amplitude and use motor for synchronous winding displacement.
Presently, most winding machine makers nonetheless use normal induction motors with inverter speed governing. This kind of motor has lower torque at lower velocity for that reason more substantial motor should be picked to make sure that at original phase the motor has enough torque for dragging thus causing issues for device miniaturization. With the ongoing development of technological innovation, this type of driving methodology is becoming replaced by servo mechanism which is equally reputable, more compact and with much better pace tuning abilities.
The look of a winding equipment is demonstrated in Figure 1.

three. Description of operating basic principle of a winding machine
Soon after winding equipment starts, all cylinders are reset. A single cylinder-pushed wire displacement system moves fully to the proper to the original placement via a slide system. Wire displacement motor returns to house placement. In the meantime winding motor rotates to preliminary angle situation. Right after the wires are put appropriately, winding motor starts, meanwhile wire displacement motor follows, when laps reach the set benefit, the wire displacement motor reverses until finally preferred amount layers of winding is arrived at.
four. Dorna servo parameter configurations
Winding machine uses synchronous wheels for transmissions which maintains a constant transmission ratio and has shock absorption and shock decreasing capabilities. On condition of no stunning, enhance velocity loop proportional obtain parameters and lessen velocity loop integral acquire and placement loop achieve parameters to steer clear of overshooting.
Parameter options for Dorna servo management method employed on a certain ZheJiang winding machine are offered beneath.

PA4= (management mode assortment, : placement control)
PA9=five (motor model variety, different dependent on motors)
PA11=3000 (situation loop achieve, selection five hundred-8000)
PA14=1500 (velocity loop obtain, selection five hundred-8000)
PA15=4000 (velocity loop integral time continual, selection 500-8000)
PA31=2(enter instruction pulse multiplication numerator)
PA32=1(input instruction pulse multiplication denominator)
PA38=a thousand (current loop obtain, variety 500-8000)

Be aware: electronic equipment ratio=PA31/PA32==Ppulse / P
In which Ppulse: Variety of pulses for each revolution of the motor, i.e. variety of pulses from motor comments factors for every revolution of the motor (pulse/revolution). For a 2500-wire increment encoder, the number of opinions pulses to the driver is 2500×4=10000
P: Number of instruction pulses that require to be acquired by the servo from the host computer to permit one revolution of the motor (pulse/revolution)
5. Notes for commissioning
To guarantee reliable, steady, and appropriate procedure of the servo driver, spend interest to the subsequent matters throughout installation, commissioning, and use of the servo technique:
1) Proper wiring: Dorna servo is created with regular encoder wires and motor power wires. Even so, during wiring, often make certain to correct the signal wires between the servo driver and the controller, or else the servo will not purpose normally
two) Set appropriate servo control manner: As each and every variety of device has different programs, proper location of servo management manner is the precondition for regular operation of the servo
3) Match gain parameters correctly dependent on actual procedure results. Besides, Dorna servo ought to not set electronic position loop and equipment ratio parameters in servo enabling mode or throughout procedure of the motor
four) Ensure proper grounding of the motor. Join the driver to products enclosure to steer clear of disturbance and leakage present.
5) Sign wires ought to adopt shielded twisted pairs as considerably as achievable. The protect layer is generally related to terminal shell
6) Pay consideration to interference problems to stop the encoder indicators and management signals from getting disturbed. Encoder wires and signal wires ought to not be tied with each other with motor traces and electrical power offer lines or operate in the exact same wire tray with them. They need to be routed at a specific distance.
six. Conclusion
This winding device achieves maximum consumer gratification by getting edge of functions of Dorna EPS sequence like speedy reaction, exact positioning, brief location time, and stable operation. This equipment can make a entire exhibition of advantages of Dorna servos, which assists increase competitive ability of winding machines.
