"Shtrikh-2", 3D Laser scanning system With reference to the work diagram ("Sequence Chart of Control Signals" Leadshine page 8 or "Input signal timing diagram" YAKO page1), it is necessary to use interfacing method for a machine with direct control of stepping driver, see 8.1.1., and set switches in the optical isolation unit according to the following scheme: 26 Figure 16 Position of switches in the optical isolation unit for stepping drivers Leadshine M542/YAKO YKB2608 and similar Two methods of interfacing or connection are possible: with the use of optical isolation unit or without using it. First method (with optical isolation unit): find “ground” on the machine with reference to which the signals PUL+/PUL-, DIR+/DIR- (DR, PU) work. The ground terminal is normally located on power supply or on a separate board with marked with "СОМ". connect this ground to the AGND input of the optical isolation unit. connect signals from the X co-ordinate driver: PUL- (PU) to the xSTEP+ input of the optical isolation unit; DIR- (DR) to the xDIR+ input of the optical isolation unit. Important: If the ground for AGND is chosen incorrectly, the system will not work. The program will return error: Error! Data file empty or Error! Check gaging speed. Important: If the ground for AGND is chosen incorrectly, the system will not work. The program will return error: Error! Data file empty or Error! Check movement speed Also, check signal levels to which the optical isolation unit is connected. If the signal level is higher than +7V, the optical isolation unit will fail to function.
