Leadshine Stepper Driver
The DMA860H is a high performance microstepping driver based on pure-sinusoidal current control technology. Owing to the above technology and the self-adjustment technology (self-adjust current control parameters) according to different motors, the driven motors can run with smaller noise, lower heating, smoother movement and have better performances at higher speed than most of the drivers in the markets. It is suitable for driving 2-phase and 4-phase hybrid stepping motors.
1. High performance, cost-effective. 2. Supply voltage up to 80VAC or +110VDC. 3. Output current up to 7.2A. 4. Self-adjustment technology. 5. Supply voltage up to +40 VDC. 6. Pure-sinusoidal current control technology. 7. Pulse input frequency up to 300 KHz.
8. TTL compatible and optically isolated input.
9. 16 selectable resolutions in decimal and binary, up to 51,200 steps/rev.
10. Suitable for 2-phase and 4-phase motors
11. Support PUL/DIR and CW/CCWmodes.
12. Short-voltage, over-voltage, over-current and short-cicuit protection.
The DMA860H has two connectors, connector P1 for control signals connections, and connector P2 for power and motor connections.
Resolution & Current Selection:
Microstep resolution is set by SW5, 6, 7, 8 of the DIP switch as shown in the following table:
The first three bits (SW1, 2, 3) of the DIP switch are used to set the dynamic current:
