H2MD Stepper Motor Driver Terminal Machine/laser Machine/marking Machine 57/86 Stepper Motor Controller

• Introduction to H2MD Series driv.
• H2MD series drivers are high-performance stepper motor drivers newly developed using standard sinusoidal current control technology, which can effectively eliminate current ripples and restrain motor vibration, improve motor performance and prolong service life, drive voltage DC20V~DC80V can adapt to various brands at home and abroad, current less than 6.0A, outer diameter 57mm~86mm four-wire, six-wire, eight-wire two-phase hybrid stepper motor.
• Product characteristics.
• Low speed anti-shaking, ultra-low noise.
• With out-of-phase protection and overcurrent protection.
• Drive overheat protection.
• Multiple subdivisions are optional (customized services can be provided).
• Photoelectric isolation signal input.
• Input pulse frequency: 0~200KHz.
• Automatic low-power operation at rest.
• Single power input, voltage range: DC20V~DC80V.
• Note:
• Please use the input signal voltage of DC5V~DC24V.
• When connecting to the DC5V, the external resistance R1 on the way is not required.
• When exceeding the DC5V, as shown in the figure, connect the external resistor R1 and use the input current of the 10mA~20mA.
• Please use twisted pair (AWG22~20) for signal line, and the length should be controlled within 2m.
• The longer the pulse line, the lower the large frequency that can be transmitted.
• Please use a wire above AWG20~18 for the power cord. In addition, do not use the same line wiring or tie with the signal line as the power line.
• If interference occurs, please shield the motor cable and power cord with conductive tape or wire screen.
• The wrong polarity of the Dc power input will damage the driver circuit.
• Be sure to confirm the polarity before powering on.

Output current selection:

H2MD series driver output current value is 6A/ phase (peak), with a total of 8 current levels with three-bit dial switch, from (MD806) 1.8A-6A, (MD803) 0.9A-3A, (MD801) 0.45-1.5A, (see table below) to match different motors.

Main application areas:

It can be widely used in engraving machine, typing mark, labeling machine, cutting machine, welding machine, cutting machine, plotter, micro machine tool, precision equipment and so on.
