The stepper motor parameters in the computer wood engraving machine are related to the speed and precision of the engraving machine. Under normal circumstances, the number of subdivisions of the stepper driver is set. Generally, the higher the subdivision number, the higher the control resolution. However, if the number of subdivisions is too high, it will affect the maximum feed rate. For the mold machine users can consider the pulse equivalent of 0.001mm / P (the maximum feed rate is 9600mm / min at this time) or 0.0005mm / P (the maximum feed rate is 4800mm / min); for the precision requirements of woodworking engraving machine For high users, the pulse equivalent can be set larger, such as 0.002mm/P (maximum feed rate is 19200mm/min) or 0.005mm/P (maximum feed rate is 48000mm/min). For a two-phase stepper motor, the pulse equivalent calculation method is as follows: pulse equivalent = screw pitch ÷ subdivision number ÷ 200.
Setting of take-off speed: This parameter corresponds to the take-off frequency of the stepper motor. The so-called take-off frequency is the highest frequency at which the stepper motor can start work without acceleration. Reasonable selection of this parameter can improve the processing efficiency, and can avoid the low-speed segment where the stepper motor has poor motion characteristics; however, if the parameter is selected to be large, it will cause a boring car, so it is necessary to leave a margin. In the factory parameters of the motor, the take-off frequency parameter is generally included. However, after the wood engraving machine is assembled, the value may change and generally decline, especially when doing load movement. Therefore, the setting parameter is preferably determined after referring to the factory parameters of the motor.
Only by setting the relevant parameters of the woodworking engraving machine, and then according to the operation process, the processing efficiency can be improved, and the service life of the engraving machine can be further improved.
