QD-5742 two-phase hybrid stepper motor driver/driver card/stepper

Certification : NONE Origin : Mainland China I. Overview --- type subdivision two-phase hybrid stepping motor driver adopts DC 18 ~ 50V power supply, suitable for driving voltage 24V ~50V, current less than 4 . 0A outer diameter 42 ~ 86 mm Two-phase hybrid stepping motor. This driver uses full digital current loop for subdivision control, and the torque fluctuation of the motor is small, the operation is stable at low speed, and the vibration and noise are low. Relatively high torque can be output at high speed, and the positioning accuracy is high. Widely applicable to engraving machines, CNC machine tools, packaging machinery, transmission equipment and other equipment with high resolution requirements main features: 1 average current control, two-phase harmonic current drive output 2 DC 18 ~ 50v power supply 3 photoelectric isolation signal input/output 4 with overvoltage, undervoltage, overcurrent and interphase short circuit protection function 5 16-gear subdivision and automatic semi-flow function 6 Eight-gear output phase current setting 7 has offline function 8 high starting speed 9 high speed torque I.
