Goodrive35-07 Product introduction As a high-performance close loop vector inverter, Goodrive35-07 inverter special for tension control uses the tension control module in the algorithm, realizing the tension control in the process of wrapping up/off. Goodrive35-07 inverter special for tension control can not only constitute a tension control system by completely replacing torque motor, DC motor and tension controller, but also compared with the traditional tension controller plus inverter control scheme, it can make the system more concise, reduce cost, easy to maintain and get more stable...

Open loop tension control in speed mode It is applicable to the situation of GD35-07 as the master and tension feedback signal in no need, and with coil diameter Count the coil diameter through the PG card or optoelectronic switch to count the circle calculation, it can realize constant linear speed control. The schematic diagram is shown below: The coil diameter changes by 0.1mm increment increasingly, and compared with the method of counting the coil diameter at a time after a circle variation, the method is more stable. Materials linear speed Count the frequency according to linear speed...

Application of jig dyeing machine The slasher is an important process in textile industry. After boiling the slurry, when the temperature reaches the value, In textile industry, the process of jig dyeing machine is to dye the cloth and it decides the appearance and color out sizing through the high temperature slurry tank into the dryer and finally wrap up for next operation. transfer the slurry to the slurry tank, then wind up the yarn at wrapping off side through the traction of the motor, carry of the cloth directly. The process requirements are: Flow chart (1) Wrap up and off at...
