ZF210 Series VFD Small Power Dedicated Frequency Converter For Textile Machinery

ZF210 Series VFD Small Power Dedicated Frequency Converter For Textile Machinery Industry

This low-power frequency converter is designed specifically for textile machinery, using advanced sensorless vector control algorithm, compatible with V/F control mode, supporting 150% high starting torque output at 1Hz and low-speed load compensation technology, ensuring that the motor can maintain strong and stable output torque even at low speeds. The product has a power range of 0.4-3.7KW and is compatible with single-phase 220V and three-phase 380V power supplies. It can be widely used in textile equipment such as carding machines, yarn drawing machines, spinning machines, warping machines, and sizing machines.

Textile machinery has extremely high requirements for motor control and needs to address the following challenges:

Multi process collaborative control: Textile production involves multiple processes such as cleaning, carding, drawing, roving, spinning, and winding, and the speed of each link needs to be accurately matched to avoid problems such as yarn breakage and tension fluctuations.

Low speed and high torque requirements: For example, the spindle of the spinning machine needs to maintain high torque during low-speed operation to prevent yarn breakage; The carding machines Xilin and Daofu need to maintain a stable speed to improve the combing effect.

High dynamic response requirements: For example, the winding machine needs to quickly respond to changes in yarn tension, adjust winding speed, and prevent yarn relaxation or breakage.

Energy conservation and consumption reduction demand: The textile industry has a high proportion of energy consumption, and it is necessary to reduce the energy consumption of motors during no-load or light load operation through variable frequency speed regulation.

Adaptability to harsh working conditions: The cotton wool in the textile workshop is flying and the humidity is high. The equipment needs to have dust-proof, moisture-proof, and anti-interference capabilities.

Efficient and energy-saving: By adjusting the motor speed to match the load demand, the phenomenon of "big horse pulling small car" is avoided, and the energy-saving rate can reach 30% -50%. For example, when applied in air conditioning systems, it can reduce power consumption and save electricity expenses.

Precise control: Supports 150% high starting torque output at 1Hz, with a frequency resolution of up to 0.01Hz, ensuring precise speed control of the motor even at low speeds and improving the quality of textile products.

Stable operation: Built in slip compensation function ensures constant motor speed for impact loads; Equipped with high and low speed load compensation function, ensuring smooth and stable start-up and operation of the motor under different loads.

Powerful protection: Built in overcurrent, overvoltage, undervoltage, overload, ground short circuit and other protection functions ensure the safe operation of the motor under abnormal working conditions and extend the service life of the equipment.

Intelligent control: Supports RS485 communication interface and MODBUS protocol, can interconnect with PLC, industrial computer and other devices, achieve remote monitoring and parameter setting, and improve production automation level.

Adapt to harsh environments: For high cotton and high humidity environments in textile workshops, the product adopts dust-proof and moisture-proof design to ensure stable operation under harsh working conditions.

Carding machine: Through frequency conversion speed regulation, precise speed control of key components such as Xilin and Dove is achieved, improving combing effect and reducing quality problems such as cotton knots and impurities.

Spinning machine: Utilizing the disturbance function of the frequency converter, the spinning speed is increased to 1600m/min, while preventing high-speed yarn separation, simplifying the mechanical structure, and reducing mechanical wear.

Spinning machine: By variable frequency speed regulation, the forming cam is removed, eliminating the phenomenon of peach bottom pause and peach top impact, improving the quality of yarn winding, and facilitating high-speed unwinding in the next process; At the same time, dynamically adjust the spindle speed according to the yarn thickness to reduce the breakage rate.

Warping machine: Utilizing the length counting and fixed length functions of the frequency converter, precise control of yarn length is achieved. When it reaches the set length, it automatically alarms and stops, improving production efficiency.

Sizing machine: Through variable frequency speed regulation, it achieves constant tension and constant line speed control of the weaving shaft winding, ensuring stable yarn tension and improving sizing quality.
