DMA860H-MainPage-5

aeProduct.getSubject()

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.

Pin Function
Details
PUL+
PUL-
Pulse signal: In single pulse (pulse/direction) mode, this input represents pulse signal, active at each rising or falling edge (set by inside jumper J3); 4-5V when PUL-HIGH, 0-0.5V when PUL-LOW. In double pulse mode (pulse/pulse) , this input represents clockwise (CW) pulse,active at high level or low level (set by inside jumper J3). For reliable response, pulse width should be longer than 1.5 us. Series connect resistors for current-limiting when +12V or +24V used. The same as DIR and ENA signals.
DIR+
DIR-
DIR signal: In single-pulse mode, this signal has low/high voltage levels, representing two directions of motor rotation; in double-pulse mode (set by inside jumper J1), this signal is counter-clock (CCW) pulse,active at high level or low level (set by inside jumper J3). For reliable motion response, DIR signal should be ahead of PUL signal by 5 us at least. 4-5V when DIR-HIGH, 0-0.5V when DIR-LOW. Please note that motion direction is also related to motor-driver wiring match. Exchanging the connection of two wires for a coil to the driver will reverse motion direction.
ENA+
ENA-
Enable signal: This signal is used for enabling/disabling the driver. High level (NPN control signal, PNP and Differential control signals are on the contrary, namely Low level for enabling.) for enabling the driver and low level for disabling the driver. Usually left UNCONNECTED (ENABLED).
