Classification Of Control Mode For Straight Line Wire Drawing Machine
- Sep 15, 2017 -

    The control system of wire drawing machine is used to control the 4-level straight-line wire drawing machine, including the Wire drawing machine of prestressed steel wires and all kinds of wire, and the system open operating parameters, so it has very wide adaptability. Control scheme point Dynamic logic, each point of the individual inverse point of the action + the "front linkage" of each point. PID control, PID input value is the feedback of all levels of tension sensor analog, P, I, D and Range parameters HMI settings, PID output value is the frequency of change, and finally the results of the PID calculation and the level of basic frequency integration into the target frequency.Straight Line Wire Drawing Machine

     Using the Intelligent control mode of PLC touch screen, all parameters can be changed by touch screen and controlled by PLC. Equipped with the corresponding button and foot switch, operators can be at the point of operation of the wire and start to stop, can also be more complex operation in the console. Air blower, oil pump, mechanical lock and other external components control optional, analog control mode and Modbus control mode is optional.Straight Line Wire Drawing Machine

    Automatic process: Press the Start button, the inverter at all levels according to the set acceleration, evenly accelerate to the set line speed, rewinding using F3000 inverter torque control. The plc is based on the tension signal PID operation, in order to ensure the operation of all levels of tension constant. Straight Line Wire Drawing Machine

    PLC will calculate the results, through the Modbus bus or da module sent to each inverter, each inverter according to the instructions of the PLC operation. Press the Stop button at any time, inverter will be set to reduce speed, uniform deceleration to 0 speed, and then hold the brake to move; any time press the emergency stop button, inverter output cut off, while the PLC output lock signal, in the case of disconnection detection signal, according to emergency stop processing.Straight Line Wire Drawing Machine

    PID detailed Description: Straight-Line wire drawing machine control of the core technology is the PID operation, we are here to adopt a more complex dynamic PID control mode, in the small power of the wire drawing system, the static PID can completely meet the requirements of control, can be changed by changing the parameters to achieve this transformation. Equal volume calculation: Due to the process of wire drawing changes in the centerline, the line speed is also changed, every second through the various levels of wire drawing die size is constant, you can get the equation (slightly) to calculate the basic frequency at all levels.Straight Line Wire Drawing Machine.
