Features: T3 Maximum control axis is 3-axis, T4 Maximum control axis is 4-axis Multiple I/O point controller mode, basic I/O is 8 input and 7 output respectively, which can extend 16*N input and output, N=1-15. Open-collector output maximum output current 500mA, can drive relay directly. Pulse orientation adopts differential output, maximum interpolation pulse output frequency 500KHZ Principal axis control mode: multi-speed (3 paragraph 8 speed, 1 channel main axis start and stop). Compatible with standard G code. support mainstream CAD/CAM software, such as ArtCam, MasterCam, ProE etc Totally independent from PC platform. Directly read files from U Disk. Multi-stage pretreatment, adaptive speed prospective control of machining path, high machining speed, high precision and good machining continuity; Small line segment is processed with high speed continuously, and the most efficient algorithm is automatically selected in many small line segment control algorithms. Acceleration and deceleration mode: S curve acceleration and deceleration Supporting the processing of documents with large capacity; Manual and automatic processing function; The function of segment hopping shall be processed according to the designated processing line number; It has the function of memory of breakpoint and automatic protection when power is off. Input/output diagnostic function, Automatic tool alignment; It has automatic return to origin and reference point Specification: Material: metal plastic Type(Optional): T3( 3-axis), T4(4-axis) Controller Size: 21.5*12*3.3cm/8.5*4.7*1.3in Interface board: 15.8*12*3.3cm/6.2*4.7*1.3in Weight: 1204g/42.5oz Package list: 1 x CNC Controller 1 x Interface Board 1 x Cable 1 x U disk Package List 1T3 Maximum control axis is 3-axis, T4 Maximum control axis is 4-axis 2Multiple I/O point controller mode, basic I/O is 8 input and 7 output respectively, which can extend 16*N input and output, N=1-15. 3Open-collector output maximum output current 500mA, can drive relay directly. 4Pulse orientation adopts differential output, maximum interpolation pulse output frequency 500KHZ 5Principal axis control mode: multi-speed (3 paragraph 8 speed, 1 channel main axis start and stop).
