MA860H Digital Stepper Motor Driver | 50-110VDC 1.8-7.2A High-Performance CNC Stepper Controller
Description
It is a high-performance stepper driver implemented with pure-sinusoidal current control technology. The MA860H Digital Stepper Motor Driver 50-110 VDC with 1.8-7.5A can be used to drive 2-phase or 4-phase motors(from “NEMA 17” or “NEMA 34” size)with less noise and heat. And it can provide better performances at high speed than most of the drivers in the markets.
It works with 36-110VDC/24-80VAC voltage and can provide max 7.2A peak current. You can set the DIP switches to get the current and microsteps you need.
Owing to the above technology and the self-adjustment technology (self-adjust current control parameters) according to different motors, the driven motors can run with smaller noise, lower heating, smoother movement and have better performances at the higher speed than most of the drivers in the markets. It is suitable for driving 2-phase and 4-phase hybrid stepping motors.
Key Features
- High Performance & Cost-Effective: Delivers superior high-speed performance and efficiency at an optimal cost.
- Self-Adjustment Technology: Automatically adjusts current control parameters according to different motors.
- Pure-Sinusoidal Current Control Technology: Ensures ultra-smooth movement, lower heating, and minimal noise.
- Isolated Inputs: TTL compatible and optically isolated input architecture for signal stability.
- Automatic Idle-Current Reduction: Automatically reduces current when stationary to minimize heat generation.
- High-Resolution Stepping: 16 selectable resolutions in decimal and binary, supporting up to 51,200 steps/rev.
- Motor Compatibility: Suitable for driving 2-phase and 4-phase hybrid stepping motors.
- Control Mode Support: Supports both PUL/DIR and CW/CCW control modes.
- Comprehensive Protection: Built-in short-voltage, over-voltage, over-current, and short-circuit protection.
Benefits
- Whisper-Quiet Operation: Advanced sinusoidal commutation drastically dampens mechanical resonance and acoustic noise.
- Thermal Optimization: Automatic idle-current reduction and efficient current control keep motor and driver temperatures low during extended runs.
- Plug-and-Play Configuration: Easily configure current limits and step resolutions using straightforward onboard DIP switch tables.
- Industrial Reliability: Robust safety protections safeguard your setup against electrical faults and overloads.
Applications
- CNC Machines & Routers: Precision motion control for X-Y tables, laser cutters, and engraving systems.
- Automated Production Equipment: Ideal for pick-and-place devices, assembly rigs, and industrial labeling machines.
- High-Speed Automation: Specially adapted for applications requiring low noise, low heating, and high-speed performance across NEMA 17 to 43 motors.
