Features DMA860H is a low‑noise digital stepper motor driver with high efficiency Adopt 32‑bit technology to meet the application needs of most places Due to the built‑in micro‑segmentation technology, even in the condition of low‑segmentation, it can achieve high‑segmentation effect Runs smoothly at low, medium and high speeds, with low noise and good performance 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 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 Package List: 1 x Driver Package List 1 x Driver
