DMA860H  Performance Stepper Motor Accessories CNC Stepper Motor Driver, Stepper Motor Driver, For Stepper Motor Engraving Machines Motor Industry

<ul><li>DMA860H is a low-noise digital stepper motor driver with high efficiency</li><li>Adopt 32-bit technology to meet the application needs of most places</li><li>Due to the built-in micro-segmentation technology, even in the condition of low-segmentation, it can achieve high-segmentation effect</li><li>Runs smoothly at low, medium and high speeds, with low noise and performance</li></ul>

Specification: Item Type: Stepper Motor DriverProduct Model: DMA860H Output Current A: 2.4-7.2 Input Power Supply Voltage VAC: 18-80 Control Signal Input Current mA: 7-20 Step Pulse Frequency KHz: 0-200 Insulation Resistance milliohm : 500 Main Application Areas: Suitable for all kinds of medium and large automation equipment, such as engraving machines, cutting machines, packaging machinery, electronic processing equipment, automatic assembly equipment, etc., the application effect is particularly in the equipment where users expect low noise and high speed Instructions: 1. Micro-step Subdivision Setting: The micro-step subdivision number of the driver is set by the four DIP switches SW5-SW8. There are 16 levels of micro-step subdivision. When the user sets micro-step subdivision, the driver should be stopped first. For the specific microstep setting, please read the driver layout description 2. Output Current Setting: The output current of the driver is set by three DIP switches SW1-SW3. There are 8 levels of output current. For specific output current settings, please read the driver's layout description. 3. Automatic Half- Function: The user can set the automatic half- function of the drive through SW4. off means that the quiescent current is set to half of the dynamic current, on means that the quiescent current is the same as the dynamic current. In general use, SW4 should be set to off, so that the heating of the motor and the driver is reduced, and the reliability is improved. About 0.4 seconds after the pulse stops, the current is automatically reduced to about half 60% of the actual value, and the calorific value is theoretically reduced to 36% 4. Signal Interface: PUL+ and PUL- are the positive and negative ends of the control pulse signal; DIR+ and DIR- are the positive and negative ends of the direction signal; ENA+ and ENA- are the positive and negative ends of the enable signal 5. Motor Interface: A+ and A- are connected to the positive and negative ends of the A-phase winding of the stepping motor; B+ and B- are connected to the positive and negative ends of the B-phase winding of the stepping motor. When the A and B phase windings are exchanged, the direction of the motor can be reversed 6. Power Interface: AC or DC power supply is used, the working voltage range of DMA860H is recommended to be 48-75VAC, and the power supply is greater than 500W 7. Indicator Light: The drive has two indicator lights, red and green. The green light is the power indicator, the green light is always on when the drive is powered on; the red light is the fault indicator, and the fault light is always on when an overvoltage or overcurrent fault occurs. After the fault is cleared, the red light is off. When the drive fails, only re-power on and re-enable to clear the fault 8. Installation Instructions: The External size of The Drive Are: Approx. 151 x 97 x 51mm / 5.9 x 3.8 x 2in Installation Hole Distance: Approx. 139mm / 5.5in It can be installed horizontally and vertically, and it is recommended to install it vertically. When installing, it should be close to the metal cabinet to facilitate heat dissipation.Size: Approx. 97mm / 3.8in143mm / 5.6in 151mm / 5.9in 23.5mm / 0.9in 45.5mm / 1.8in 4mm / 0.2in 139mm / 5.5in 4.5mm / 0.2in 48mm / 1.9in 10.5mm / 0.4in Package List: 1 x Driver Note: <div>Please
