Động Cơ Bước Kỹ Thuật Số 32 Bit Dma860H 2.4 7.2a

Feature:
1. DMA860H is a low‑noise digital stepper motor driver with high efficiency
2. Adopt 32‑bit technology to meet the application needs of most places
3. Due to the built‑in micro‑segmentation technology, even in the condition of low‑segmentation, it can achieve high‑segmentation effect
4. Runs smoothly at low, medium and high speeds, with low noise and good performance
5. The drive has integrated parameter auto‑tuning function, which can automatically generate operating parameters for different motors and give full play to the click performance

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 (MΩ): 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 good 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-flow Function: The user can set the automatic half-flow 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 5
