LeadShine MA860H Microstep Driver 2/4 Phase Stepper Driver VAC18V-80V NEMA size 23 to 42Descriptions: The MA860H Stepper Driver Board Controller is a high performance microstepping driver based on pure-sinusoidal current control technology. With this technology and the self-adjustment technology (self-adjust current control parameters) for different motors, the drive motors can run with smaller noise, lower heating, smoother movement and have better performances at higher speed than most of the drivers in the markets. It is suitable for driving 2-phase and 4-phase hybrid stepping motors, so the Nema23, Nema34 and Nema42 stepper motors with a 2.6A-7.2A current will be suitable. Suitable for any small-and-medium automatic equipment with CNC controller, such as X-Y tables, labeling machines, laser cutters, engraving machines, and pick-place devices Suitable for a wide range of stepping motors, from NEMA size 23 to 42 For processing various pattern mould For advising, such as brand, architechture mould, badge, nameplate, display boards, doorplate, furniture decoration, etc. For carving portrait, scenery, handwriting, sealing, etc. Features: 1.High performance, cost-effective 2.Supply voltage from "18V AC to 80V AC" or "24V DC to 110V DC" 3.Output current from 2.6A to 7.2A 4.Self-adjustment technology, full to half current self-adjustment when motors from work to standstill via switching off SW4 5.Pure-sinusoidal current control technology 6.Pulse input frequency up to 300 KHz 7.TTL compatible and optically isolated input 8.Automatic half-current reduction as long as switching off SW4 when motors stop 9.16 selectable resolutions in decimal and binary, up to 51,200 steps/rev 10.Suitable for 2-phase and 4-phase motors 11.Support PUL/DIR and CW/CCW modes 12.Short-voltage, over-voltage, over-current and short-circuit prote
