Descriptions:

MA860H CNC Stepper Driver Board Controller 2.6-7.2A AC18-80V DC24-110V 2/4 Phase

The MA860H Stepper Driver 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 less 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.

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
16 selectable resolutions in decimal and binary, up to 51,200 steps/rev
Suitable for 2-phase and 4-phase motors
Support PUL/DIR and CW/CCW modes
Short-voltage, over-voltage, over-current and short-circuit protection, protect the PC, motors, driver etc from being damaged
External Fan Design to avoid overheat

Applications:

Suitable for any medium-and-big size 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.
