Servo drive with high speed wrapping function

A method for driving servo drive with high speed wrapping function, comprising:

• a parameter setting step, where the function parameters are set according to wrap pattern;
• an initial origin return step, where the servo drive receives an external activation signal and uses with the origin detector to detect wrap origin, a wrap origin return is performed to enter wrap function;
• a wrap thickness calculation step, the servo drive reads the thickness detection voltage signal from the potentiometer to calculate the wrap thickness and wire speed control in wrap duration;
• a rotation control step for wrapping mechanism, the servo drive calculate an inverter command based on above set parameters, wrap thickness and wire speed command, the inverter command is output to the inverter, whereby the inverter controls the induction motor to drive the wrapping mechanism;
• a lateral movement control step for wrap mechanism, where the encoder generates a series of pulse signals to the wrapping command processor according to the rotation of the induction motor, the series of pulse signals used with the wrap parameters for pulse command calculation of the servo motor and the wrap positioning control, the servo motor having forward and backward rotation to move the wrapping mechanism between two ends of the cylinder;
• and
• a wrap stopping step, where the servo drive receives an external close signal (WSTOP) to stop the rotation control unit and the lateral motion control unit.
