Dorna Servo Motor Used on Winding Machine

Software of Dorna Servos on Winding Equipment
Summary: This paper describes software of Dorna EPS sequence servo method on winding machine primarily based on evaluation of working basic principle of winding device. Configurations of critical of parameters of servo drives are also provided.
1. Introduction
Winding equipment is critical processing equipment commonly utilized in electrical and digital market. It is to use enameled copper wire to wind inductors. It is 1 piece of mechanical system demanding higher control precisions of pace and accuracy. The manage system is necessary to give extremely exact & clean line velocity and versatile commutation functionality.  winding equipment are broadly employed for manufacturing annular core voltage regulators, transformers, existing mutual inductors and so on.
There is a assortment of winding equipment including parallel winding devices, annular winding devices, stator/rotor winding devices, textile winding machines, as well as voice coil winding machines.
2. Composition of a winding machine
Higher laptop is normally SCM or PLC with text show for automated control. Use angle and revolution amount to set the magnetic ring winding amplitude and use motor for synchronous winding displacement.
Presently, most winding machine companies still use normal induction motors with inverter speed governing. This variety of motor has minimal torque at low speed therefore bigger motor need to be chosen to make sure that at preliminary stage the motor has ample torque for dragging hence triggering troubles for device miniaturization. With the constant improvement of engineering, this type of driving methodology is currently being changed by servo mechanism which is similarly reputable, scaled-down and with greater pace tuning abilities.
The look of a winding machine is proven in Determine 1.

3. Description of working theory of a winding equipment
After winding device starts, all cylinders are reset. A single cylinder-driven wire displacement system moves completely to the proper to the initial situation by way of a slide platform. Wire displacement motor returns to home situation. In the meantime winding motor rotates to preliminary angle placement. Following the wires are positioned correctly, winding motor commences, meanwhile wire displacement motor follows, when laps reach the established benefit, the wire displacement motor reverses until finally desired number layers of winding is arrived at.
4. Dorna servo parameter configurations
Winding machine uses synchronous wheels for transmissions which maintains a continuous transmission ratio and has shock absorption and shock lowering functions. On condition of no shocking, enhance velocity loop proportional obtain parameters and reduce velocity loop integral gain and place loop achieve parameters to keep away from overshooting.
Parameter options for Dorna servo control program employed on a certain ZheJiang winding device are provided below.

PA4= (control method assortment, : position control)
PA9=five (motor product choice, various dependent on motors)
PA11=3000 (position loop obtain, selection five hundred-8000)
PA14=1500 (velocity loop obtain, variety five hundred-8000)
PA15=4000 (velocity loop integral time continuous, variety five hundred-8000)
PA31=2(enter instruction pulse multiplication numerator)
PA32=one(input instruction pulse multiplication denominator)
PA38=1000 (current loop gain, assortment 500-8000)

Notice: digital equipment ratio=PA31/PA32==Ppulse / P
Where Ppulse: Variety of pulses per revolution of the motor, i.e. number of pulses from motor suggestions components for every revolution of the motor (pulse/revolution). For a 2500-wire increment encoder, the quantity of comments pulses to the driver is 2500×4=ten thousand
P: Number of instruction pulses that want to be gained by the servo from the host computer to allow a single revolution of the motor (pulse/revolution)
five. Notes for commissioning
To ensure reliable, secure, and correct procedure of the servo driver, spend attention to the pursuing matters during set up, commissioning, and use of the servo technique:
one) Appropriate wiring: Dorna servo is made with regular encoder wires and motor electricity wires. Nonetheless, throughout wiring, always make positive to proper the signal wires between the servo driver and the controller, otherwise the servo will not operate generally
two) Set proper servo control method: As every kind of machine has distinct purposes, proper placing of servo management mode is the precondition for normal procedure of the servo
three) Match achieve parameters properly relying on real operation outcomes. In addition to, Dorna servo should not set digital position loop and equipment ratio parameters in servo enabling mode or for the duration of operation of the motor
4) Guarantee suitable grounding of the motor. Hook up the driver to products enclosure to stay away from disturbance and leakage recent.
5) Sign wires must undertake shielded twisted pairs as considerably as attainable. The protect layer is generally connected to terminal shell
six) Spend interest to interference problems to avert the encoder signals and control indicators from becoming disturbed. Encoder wires and sign wires must not be tied jointly with motor traces and energy provide lines or operate in the same wire tray with them. They need to be routed at a certain length.
6. Summary
This winding device achieves optimum consumer fulfillment by having edge of features of Dorna EPS sequence like quick reaction, exact positioning, quick setting time, and stable procedure. This tools tends to make a entire exhibition of rewards of Dorna servos, which will help enhance aggressive potential of winding machines.
