ZF-D200 Series Textile Machinery Servo Drive Systems

The servo system of textile machinery is one of the core technologies for achieving efficient and precise production in modern textile industry. It achieves high-precision control of textile machinery movement through the collaborative work of servo motors, drivers, controllers, and feedback devices.

1. Core Components

• Servo Motor: Adopting permanent magnet synchronous motors or asynchronous motors, with high speed, high torque density, and fast response characteristics, it can adapt to the high-speed and high-precision motion requirements of textile machinery.
  Driver: Responsible for converting control signals into motor drive signals, supporting three control modes: position, speed, and torque, and possessing functions such as overload protection and fault diagnosis.
  Controller: Based on PLC or dedicated motion control chips, achieve multi axis collaborative control, trajectory planning, and process parameter adjustment, and support fieldbus communication (such as EtherCAT, CANopen).
  Feedback device: Using encoders (such as photoelectric encoders, magnetic encoders) or rotary transformers to provide real-time feedback on motor position and speed information, forming a closed-loop control.

2. Key Features

• High precision control: Through closed-loop feedback and advanced control algorithms, a position accuracy of ± 0.01mm and a speed accuracy of ± 1rpm are achieved, meeting the stringent requirements of textile machinery for parameters such as yarn tension and fabric density.
  Fast dynamic response: The response time of the servo system is usually less than 5ms, which can quickly adjust the motor speed and torque, and adapt to the frequent start stop and acceleration/deceleration requirements in textile technology.
  Energy saving and efficient: By adopting vector control and weak magnetic control technology, the motor efficiency can reach over 95%, significantly reducing energy consumption.
  Reliability: Having a protection level of IP54 or above, suitable for high temperature, high humidity, and dusty environments in textile workshops; The driver has built-in protection functions such as overvoltage, undervoltage, overcurrent, and overheating.

3. Applications

• Spinning equipment
  Spinning machine: precise control of yarn density is achieved by controlling the spindle speed and roller drawing through a servo system.
  Drawing machine: using servo motors to drive the pressure roller and loop bar, optimizing the uniformity and weight deviation of the cotton strip.
  Weaving equipment
  Rapier loom: The servo system drives the weft insertion rapier and warp feeding mechanism to improve the accuracy of fabric weft density and weaving efficiency.
  Jet loom: By servo controlling the air pressure of the main nozzle and auxiliary nozzle, high-speed and low-energy weaving is achieved.
  Printing and dyeing equipment
  Dyeing machine: The servo system controls the dye circulation pump and fabric transmission roller to ensure dyeing uniformity and color fastness.
  Forming machine: It uses servo motors to drive the oven air door and roller pressure, achieving fabric size stability and hand feel optimization.
  Knitting equipment
  Circular knitting machine: The servo system controls the needle triangle and yarn feeding mechanism to improve the density and pattern accuracy of knitted fabrics.
  Warp knitting machine: It drives the comb and jacquard device through servo motors to achieve high-speed weaving of complex patterns.
