Overview The MA860H is a high performance microstepping driver based on pure-sinusoidal currentcontrol 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. Key Features High performance, cost-effective Supply voltage up to 80VAC or +110VDC Output current up to 7.2A Self-adjustment technology Pure-sinusoidal current control technology Pulse input frequency up to 300 KHz TTL compatible and optically isolated input Automatic idle-current reduction 16 selectable resolutions in decimal and binary, up to 51,200 steps/rev Suitable for 2-phase and 4-phase motors Support PUL/DIR and CW/CCW modes Short-voltage, over-voltage, over-current and short-cicuit protection Electrical properties (ambient temperature Tj = 25C pm) Parameters MA860H Min.

In double pulse mode(pulse/pulse) , this input represents clockwise (CW) pulse,active at high level or low level (set by inside jumper J1 & J2). For reliable response, pulse width should be longer than 1.5?s. 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 & J2), this signal is counter-clock (CCW) puls. For reliable motion response, DIR signal should be ahead of PUL signal by 5?s at least. 4-5V when DIR-HIGH,0-0.5V when DIR-LOW. Please note that motion direction is also related tomotor-driver wiring match. Exchanging the connection of ?two wires for a coilto 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 fordisabling the driver.

Therefore, output current is generally set to be such that the motor will not overheat for long time operation. Since parallel and serial connections of motor coils will significantly change resulting inductance and resistance, it is therefore important to set driver output current depending on motor phase current, motor leads and connection methods. Phase currentm rating supplied by motor manufacturer is important in selecting driver current, however the selection also depends on leads and connections. The first three bits (SW1, 2, 3) of the DIP switch are used to set the dynamic current. Select a setting closest to your motor’s required current.
