BIẾN TẦN AC90 ĐIỀU KHIỂN LỰC CĂNG Hoạt động ổn định với tất cả các loại động cơ và chế độ điều khiển: V/F, SVPWM, Sensorles Vector, Vector Control

AC90 tension control inverter to achieve constant tension control via adjusting output torque and automatically roller diameter calculation. Need no tension sensor installation which uses feedback current external position and tension signal. Even it can achieve tension control without installing speed feedback encoder in mostly application.

It employs advantage torque identification calculating with compensate rotational inertia automatically, static and slip friction forces function to realized consistently tension characteristic for whole material processing. Adopts intelligence roller identification technology with highly precision identification, strong anti interference ability

Speed control mode: Regulating output frequency of inverter to change the speed of motor.

Torque control mode: Regulating the motor output torque, the speed determined by load condition, but will limit to a setting frequency. The user can preset the tension value to achieve the tension control via built in roll diameter calculating.

AC90 tension control inverter suits wind and unwind application of film splitter, printing, printing coater, packing machine with simple control system and easy maintenance.

It is available to built a better tension control system for replacing torque motor, DC motor and tension control system. 

1. Outstanding performance

High accuracy output torque linearity

A variety of tension setting modes, kinds of coil diameter calculation, various dynamic compensation, which make AC90 inverter completely instead of tradition tension system that constitute with torque motor, DC motor and tension controller. Make tension control system more concisely and ease of maintaining.

2. Excellent performance date

Torque control in open loop vector control ( OLV)

Torque control in close loop vector control (CLV)

Torque control and speed control switching.

Torque accuracy is ±3% in OLV

Torque accuracy is ±2% in CLV

Torque response time less than 20ms in OLV

Torque response time less than 10ms in CLV

3. Reliability design

Protective PCB coating (moisture proof, mould proof and salt proof painting )

Wide range voltage input

Independent air duct design

Removable fans for easy change, clean and maintenance

4. Rich expand function
