HBS86H 2‑Phase Hybrid Servo Driver, 50–100 VDC Input, Up to 8.2 A Output Current, Closed-Loop Stepper Control

The HBS86H is a cost-effective hybrid servo driver that blends the benefits of stepper and servo motor control. It features a high-speed (~50 µs) optical encoder feedback loop, enabling real-time position correction. This allows for high torque even at low speeds, minimal vibration, and no missed steps. Suitable for driving NEMA 34 hybrid stepper motors, it supports both AC (20–70 VAC) and DC (30–100 VDC) supply, and is ideal for CNC, robotics, and precision automation systems.

Key Features:

• Wide input compatibility: Accepts 30–100 VDC (or 20–70 VAC), enabling flexibility across power sources.
• High peak current: Delivers a peak output of 8.2 A, offering strong torque performance.
• Closed-loop performance: Uses encoder feedback to prevent step loss and tune motor control dynamically.
• No tuning required: Built-in stability avoids hunting and simplifies setup.
• Fast response and smooth motion: Offers immediate reaction, minimal settling time, and ultra-low noise operation.
• Robust protection features: Includes over-current, over-voltage, and position following error safeguards with LED alerts.
