2Phase Stepper Motor Driver

1. AC110v power input. Suitable for high-speed high torque applications.
2. Can specify driving current, reaching highest reading of 1.5A per phase.
3. uni-polar constant current 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.
