Step forward motor drive breakdown
Several segmentation is equivalent to "accuracy" increased several times (each pulse motor rotation Angle is small, the execution of losing a few pulse generated by the error is small, the control precision is high), if you want to keep constant speed, the frequency will increase accordingly. For example, the motor turns a circle with 200 pulses, you do 2 subdivisions, and then the motor turns around 400 (200 * 2) pulses The average subdivision is 2, 4, 8, 16, 32 Maybe 64, 128, too. General plus segmentation is in order to improve the control precision, but the segment is the increase in state of electrical pulses to improve its accuracy, in fact segmentation also exist error, but it has error precision machinery manufacturing, this cannot be completely avoided.
Stepper driver segment, is the concept of electronic gear ratio, by setting segmentation can pulse equivalent, but the running speed of the motor and control the main pulse frequency, if 8 segment to obtain 1 segment at the same speed, you need to eight segments of the control pulse frequency is 1 when the frequency segment 8 times.
Speed is ok with subdivision, speed is related to the frequency of your pulse input, please increase your pulse input frequency so that you can improve speed!
