LeadShine MA860H Microstep Driver 2/4 Phase Stepper Driver VAC18V-80V

Description:

- 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:

- High performance, cost-effective

- Supply voltage from "18V AC to 80V AC" or "24V DC to 110V DC"

- Output current from 2.6A to 7.2A

- Self-adjustment technology, full to half current self-adjustment when motors  from work to standstill via switching off SW4

- Pure-sinusoidal current control technology

- Pulse input frequency up to 300 KHz

- TTL compatible and optically isolated input

- Automatic half-current reduction as long as switching off SW4 when motors stop
