Feature: 1. LOW NOISE: Adopt digital DIP technology, bring ultra low vibration noise, built in high subdivision 2. LOW HEATING: Automatic parameter setting function, accurate current control makes the motor heating greatly reduced, static current automatically halved 3. POWERFUL FUNCTION: Can drive 4, 6, 8 line two phase stepper motor, support optical isolation differential signal input 4. FREQUENCY AND CURRENT: Impulse response frequency is up to 200KHz, current setting is convenient, the maximum is 2.2A, resolution is 0.1A 5. GOOD PROTECTION: Easy subdivision setting, range from 200~51200, with over voltage, short circuit and other protection functions 6. FOR AUTOMATIC EQUIPMENT INSTRUMENTS: Such as engraving machine, marking machine, cutting machine, laser phototypesetting, plotter, CNC machine tools, automatic assembly equipment, etc., particularly effective in applications where users expect low noise and high speed Specification: Item Type: Stepper Motor Driver Output Current(peak): Minimum: 1A, Maximum: 2.2A Input Voltage: Minimum: 20VDC, Typical: 24VDC, Maximum: 40VDC Control Signal Input Current: Minimum: 7mA, Typical: 10mA, Maximum: 16mA Step Pulse Frequency: Minimum: 0KHz, Maximum: 200KHz Insulation Resistance: Minimum: 500MΩ Cooling Mode: Can not be placed next to other heating equipment, avoid dust, oil mist, corrosive gas Occasion: Too large humidity and strong vibration place, no combustible gas and conductive dust Temperature: 0 to 50 ℃ Humidity: 40-90% RH Vibration: 10 ~ 55hz / 0.15mm Storage Temperature: -20 ℃ to 65 ℃. Package List: 1 x Stepper Motor Driver Note: The driver does not have the reverse connection protection function of the positive and negative power poles. Therefore, ensure that the positive and negative power poles are correctly connected before powering on the driver. The reverse connection of positive and negative terminals will cause the fuse to short circuit protection in the burned drive.
