How to Use / Setup Instructions

1. Mounting & Wiring:

   • Install the driver in a control cabinet with proper ventilation. For best cooling, mount vertically and consider forced convection if needed.woodstar.in

   • Connect power (18–80 VAC or 24–110 VDC), motor phases (A+, A–, B+, B–), and control signals to the DIN connectors.

2. Select Control Mode:

   • Configure mode via jumpers: choose between PUL/DIR or CW/CCW control; set active edge (rising/falling) with J1/J2; reverse direction with jumper J3.Studocuwoodstar.in

3. Configure DIP Switches:

   • SW5–SW8: Set desired microstep resolution (e.g., 400–51,200)StudocuAmkit Group

   • SW1–SW3: Set peak current level (choices from 2.4 A to 7.2 A).Amkit Groupsalecnc.net

4. Power On & Auto-Tune:

   • Power the system without input pulses.

   • Toggle SW4 twice (OFF→ON→OFF or vice versa) within one second to initiate auto-tuning.Studocu

5. Connect Pulse Inputs:

   • Use shielded twisted-pair cables for PUL, DIR, ENA signals.

   • Maintain at least 10 cm separation between control cables and motor wires to avoid interference.StudocuCNC24H.COM

6. Operation & Safety:

   • Ensure ENA precedes DIR by ≥ 5 µs and DIR precedes PUL by ≥ 5 µs for accurate motion.StudocuManualsLib

   • Avoid hot-swapping motor connectors under power to prevent damage due to back-EMF.Studocu
