1. The drawing motor of the drawing machine adopts S011Z3 inverter, and the winding motor adopts S004G3 special winding inverter (the external braking resistor uses the operation command and output frequency signal of the master INV1 as the operation command of the slave INV2 and Frequency command realizes synchronous operation
2. When parking, brake in the opposite direction for a heavy full plate to prevent disconnection caused by inertia
3. Use JOG function to realize the jog work during threading operation.
