Features

Benefits

For Wire-drawing Machine

• Operation without swing link: It adopts open loop tension control to realize operation without swing link under speed sensorless control mode.
• Operation with swing link: The user does not need to adjust the position of the swing ink manually. When the system starts up, the swing link will get to the proper position automatically.
• Powerful tensile capacity: It is suitable for the applications of large and medium wire-drawing machine. It features large torque upon low frequency operation and high speed stabilization precision.
• Double conversion scheme: It can realize the inverter application of the same power class with precise current control and does not need to upgrade the level.

Environment adaptability: Independent duct design, protective coating treatment, high-temperature operation, and digital protection function.

For textile machine

• Traverse operation function: It can effectively lead the yarn into the yarn carrier on the yarn and chemical fiber equipment to prevent the overlapping of the yarn and facilitate the unreeling.
• Constant line speed mode: It can effectively prevent the uneven tightness of the yarns from the high speed cone winder to maintain the constant tension.
• Fixed length calculation: It is convenient for the user to calculate the thread length.When the thread length reaches the preset value, the equipment will be shut down automatically.
• Fixed diameter shutdown: The spindle diameter can be detected by inputting analog signal. When the preset value is reached, the equipment will be shut down automatically.

Crawling positioning: When the spinning is interrupted or ended, it can decelerate the equipment to designated frequency for low-speed operation and then shut down the equipment when receiving the positioning signal.
