2phase Stepper Motor Driver

1. AC110V, power input. Suitable for high-speed high torque applications.
2. Can specify driving current, reaching highest reading of 2.0A per phase.
3. Constant current uii-polar driving method, suitable for 6-lead-wire or 8-lead-wire 2-phase step motors.
4. Excitation mode can be selected from full-step or half-step.
5. Provide two methods of pulse input: Single-pulse(1p), and two-pulse(2p).
6. Can adjust running current and stop current for optimal motor revolving performance.
7. Overheating protection and output to ensure product safety.
8. Auto-current-down function for reduced motor heat.
9. Step zero output, and motor current off (cof) functions, can be used for external control.
10. Self-testing function.
11. High speed cpld component design, enhances stability of product.
12. Drive current using soft-up method to prevent sudden burn-out of driver.
13. LED displays revolving status. Input and output both use photo.
14. Coupler to provide noise isolation.
15. Special design of large aluminum alloy extrusion heat sink body.
