[QUOTE="dreambox1959, post: 1164425, member: 314801"] on most conventional actuators the pulse duration is at most 3ms. on the EGIS motor this duration becomes 0.6ms. i have recently been using a mini motor to build a polarization motor the pulses are 0.3ms!!! if we want to increase the precision by increasing the number of pulses the µP program must be able to count 10 times faster!! otherwise it will lose pulses!!! i could not read the v-box program but I doubt it is fast enough. another common problem, the parasites caused by the motor, it is necessary to put a 100nF/63V capacitor and a VDR at the motor terminal and the faults will disappear.
