6A closed loop Stepper Drive 30-100VDC with Full Position Feedback

6A closed loop Stepper Drive with Wide DC Supply Range

The 6A closed loop Stepper Drive 2HSS86H is rated at 6 A maximum output current and accepts a supply from 30-100 VDC or 24-75 VAC, giving installers flexibility in how the motion bus is powered. It applies full closed loop control across its current, speed, and position loops, combining servo-like feedback with standard stepper drive simplicity. Lyenwsin supplies this drive for automated handling, packaging, and industrial automation equipment.

Supply Flexibility and Continuous Duty

A wide DC input window means the same drive model can be powered from different machine DC rails without reconfiguration. Because the closed loop commands phase current based on load, the drive stays efficient at standstill, generating less heat and lower audible noise than an overdriven open-loop stage. This suits machines that dwell between moves for long periods.

Load and Position Recovery

Position feedback lets the drive detect and correct load-induced lag promptly. For NEMA34-class motions in medium-size equipment, this reduces scrap from lost position and allows closer-to-peak torque usage without extra safety margin on every step.

Commands and Interfacing

Pulse/direction inputs keep the drive compatible with step-based controllers. While pulse trains are typically point-to-point, the drive remains a deterministic single-axis positioning stage inside a larger automation network.

Key Specifications

• Output current: max 6 A
• Supply voltage: 30-100 VDC / 24-75 VAC
• Control mode: Pulse/Dir
• Feedback: full closed loop control
• Operation: high efficiency, low heat, low noise

Typical Applications

The drive fits industrial automation, packaging and printing lines, compact CNC equipment, robotics, textile machinery, automated handling, and food processing where a robust single-axis drive must hold position reliably under a variable power supply.

Selection Considerations

Verify the motor phase current is within 6 A and confirm the supply arrangement, DC or AC, matches the machine’s existing infrastructure. Lyenwsin can help select the correct NEMA34 motor partner and provide configuration guidance for your controller.
