Product Overview
Core Function & Application
Digital stepper drives are electronic controllers that convert low-level signals from microcontrollers or computers into high-current, high-voltage signals to drive stepper motors. They are widely used in 3D printers, CNC routers, textile machinery, and precision positioning equipment—applications that require accurate motion control and stable step operation. Available in voltage-controlled, current-controlled, and integrated types, they unlock the precise positioning capabilities of stepper motors.
Key Product Value
They balance cost-effectiveness and performance, providing open-loop control (no need for feedback devices like encoders) to simplify system design while supporting microstepping for smooth motion—ideal for small to medium-precision industrial and hobbyist projects.
Product Advantages
• Microstepping Capability: Most models support microstepping, which divides each full step of the stepper motor into smaller incremental steps. This improves motion smoothness, reduces vibration, and enhances positional accuracy, especially at low speeds (critical for 3D printing and CNC engraving).
• Open-Loop Operation: No encoders or resolvers are required to determine the motor’s position, simplifying system design and lowering overall costs compared to closed-loop servo drive systems.
• Flexible Current & Pulse Setting: Adjustable current output (from 2.00A to 7.20A) and pulse-per-revolution (from 400 to 40000) to match different stepper motor models and positioning requirements.
• Cost-Effectiveness: More affordable than servo drives, making them suitable for applications that need precise but non-continuous motion control (e.g., automatic feeding mechanisms, positioners).
• Easy Integration: Compatible with most microcontrollers and PLCs, with clear wiring interfaces (e.g., PUL, DIR, ENA signals) for quick integration into existing control systems.
Technical Specifications
Current Output Parameters
• Current Range: Adjustable from 2.00A to 7.20A, set via dip switches (SW1-SW3). For example:
◦ 2.00A when SW1-SW3 are in specific off/on combinations.
◦ 3.77A with SW1 on, SW2 on, SW3 on.
◦ 7.20A when SW1-SW3 are all off (for high-power stepper motors).
• Current Control: Supports stable current output to prevent motor overheating and ensure consistent torque.
Pulse & Signal Parameters
• Pulse-per-Revolution (Pulsel/rev): Adjustable from 400 to 40000 via dip switches (SW5-SW8). Common settings include 400, 800, 1600, 3200, 6400, 12800, 25600, 51200, 1000, 2000, 4000, 5000, 8000, 10000, 20000, and 40000—adapting to different positioning precision needs.
• Signal Interfaces: Includes PUL (pulse), DIR (direction), and ENA (enable) signals, with clear positive/negative (e.g., PUL+, PUL-) connections for reliable signal transmission.
Voltage Compatibility
• Input Voltage: AC 20V to 80V, supporting common industrial AC power supplies and ensuring stable operation across different voltage fluctuations.
