JK0215 two-phase stepper motor drive is to use the patent technology research and development of segment type high-performance stepper motor drives, suitable for driving any small to medium size 1. 5 a phase current two or four phase hybrid stepping motor. Due to the use of new type double polarity constant current chopper drive technology, using the same motor drive mode output can be compared to other more speed and power. JK0215 segmentation function to improve step motor running accuracy by 164 times. Twenty thousand times per second, chopping frequency, can eliminate the chopper drive noise. Another unique feature is still reduced flow: when the motor in a stop state, the output current can be automatically fell to lower end, thus reducing the motor and the drive of fever. To meet the users in the pulse frequency is not high under the condition of low speed high segment, high speed low segment, PC to test drive the output of the first FSTEP step signal, such as the whole step signal effectively, then PC output new fine fraction (MS2、MS1、MS0), wait for the next step, drive to new work fine fraction. Dynamic change segment, the segment selector switch SW4, SW5, SW6 must be placed in one state, use the computer after the initialization, should be in front of the output pulse, set the fine fraction (MS2、MS1、MS0)。 Such as MS2, MS1, MS0 1 status for the whole, the drive does not work, until the MS2, MS1, MS0 from full 1 state.
