Feature:_x000D_ _x000D_ It can drive three 2.5A stepper motors at the same time. It is convenient for you to expand the 5th axis when you need 5-axis processing. _x000D_ High-speed Optocoupler DCDC is totally isolated, which really protects your computer. _x000D_ Spindle relay output, easy to use Mach3 and other software to control the start and stop of the spindle. _x000D_ Half-current control function can effectively reduce the current to the lowest when the motor stops _x000D_ With fan interface, fans can be added at will. _x000D_ It has 4 channels of 0.8-3.5A (peak value) adjustable current rated output two-phase bipolar stepper motor drive. _x000D_ Standard parallel interface, supporting a series of software such as MACH2, KCAM4, etc _x000D_ With four-way limit interface, the plug-and-pull joint design is convenient for you to understand the limit switch. _x000D_ Supporting four working modes: mixed mode, fast mode, slow mode and normal mode. _x000D_ Supporting four subdivisions: 1, 1/2, 1/4, 1/16. _x000D_ 24-36V single power input uses switching power supply chip as 5V power supply, stable and fever is small. _x000D_ _x000D_ Specification:_x000D_ Model: TB6560_x000D_ Type: 3-Axis_x000D_ Working model: Mixed mode, fast mode, slow mode and normal mode_x000D_ Weight: 611g / 21.6oz_x000D_ _x000D_ Package list:_x000D_ 1 * Stepper Motor Driver_x000D_ 1 * Parallel wire_x000D_ _x000D_ Note:_x000D_ The actual product color may deviate from the photo due to light._x000D_ There may be a slight deviation in the measurement of product.
