rewinding of the inverter, to keep constant tension of winding and
rewinding cable.
Drawing machine can divide into large drawing machine, medium
drawing machine, slender drawing machine and micro drawing
machine other four, composes of drawing and taking-up two parts. To
improve the quality of cable and lower the cost, drawing machine is
general from single frequency control to dual-frequency control, and
now most of the dual-frequency control is generally used external PID
control board, the shortcomings of this approach are: the control
parameters of PID board is difficult to debug, the control performance
depends on the level of debugging skill; Too many components and
adjustable potentiometers on the PID board are more prone to damage,
repair and maintenance costs are high.
