The stepper motor parameters in the computer carpenter 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. 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 moment) or 0.0005mm / P (the maximum feed rate is 4800mm / min at this moment); the accuracy of the carpenter engraving machine is not high Users, the pulse equivalent can be set larger, such as 0.002mm / P (the maximum feed rate is 19200mm / min at this moment) or 0.005mm / P (the maximum feed rate is 48000mm / min at this moment). Regarding the two-phase stepping 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 that the stepper motor can start directly without speeding up. Reasonable selection of this parameter can improve the processing power, and can avoid the low-speed section of the stepper motor with poor motion characteristics; however, if the parameter is selected large, it will form 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 carpenter engraving machine is installed, the value may change, generally falling, especially when doing load movement. Therefore, the setting parameter is preferably after the reference to the motor factory parameters, and then the actual measurement resolution.
As long as the relevant parameters of the computer carpenter engraving machine are set, and then produced according to the operation process, the processing power can be better improved, and the service life of the engraving machine can be further protected.
