n Digital Control Machine Tool
u Compact structure: The size is equal to 70% of the inverter of the same power.
u Low speed precise processing: The excellent low-frequency torque performance can meet the processing demand of the machine main shaft in low speed condition (when it is operating in motoring state, it can realize a frequency as low as 0.25Hz and output 180% rated torque).
u Torque and rotating speed index: It can meet the sudden loading and unloading requirement upon the cutting processing, with the dynamic torque response time <20ms and speed stabilization precision of ±0.2%.
n Special Function for Wire-drawing Machine
u Operation without swing link: It adopts open loop tension control to realize operation without swing link under speed sensorless control mode.
u Operation with swing link: The user does not need to adjust the position of the swing link manually. When the system starts up, the swing link will get to the proper position automatically.
u 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.
u 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.
u Environment adaptability: Independent duct design, protective coating treatment, high-temperature operation, and digital protection function.
n Special Function for Textile
u 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.
u 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.
u 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.
u 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.
u 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.
n Extrusion Machine Energy Saving
u Extrusion machine interface board: It can realize best flow and pressure distribution relation in different processes by receiving the extrusion machine feedback signal to realize the optimized energy saving control of the motor.
u Customized process curve: The user does not need to change the inverter parameter when replacing the moulds. The process curve memory can be easily realized.
u Wide range torque output: Within the set range of pressure and flow, the motor torque output is stable to ensure the quality of the workpiece.
u Tripless: With extremely powerful loading capacity, the inverter can realize stable tripless operation in any acceleration/deceleration time and under any impact load condition.
u Green output: It adopts advanced power module drive mode to reduce the interference to the extrusion machine control circuit and sensor.
n Lifting Control
u Step torque response: It can quickly follow the equipment load change to prevent the runaway situation and ensure the safe production.
u Four quadrant operations: It can smoothly and quickly switch the forward and reverse motoring and generating state of the equipment.
u Torque monitoring: It can adjust, limit, display and switch the torque output, so as to monitor the operating state of the equipment.
