ik 6019 a 9 december 2011 , ver. 00 functional description the ik 6 019 a provides 3 stepping modes setting as shown in the table below. the stepping mod e depends on signals dir1 and dir2 at the falling edge of the first pulse of in1 (in2): dir1 dir2 stepping mode 1 1 single stepping 1 0 half stepping 0 0 high torque stepping the second pulse of in1 (in2) (time from falling edge till raising edge) de termines the duration of the outputs operation, whereas the next time from raising edge till falling edge sets the delay time between output channels in depend on stepping mode. after changing direction (dir1 (dir2) falls from 1 to 0 or rises from 0 to 1), outputs out1_1 to out1_4 (out2_1 to out2_4) are turned off and will be switch ed at the next pulse of in1 (in2) in according with stepping mode. if the input reset changes the level from high to low, all outputs and internal triggers are turned o ff. after returning the high level to the input reset, it is needed to determine the stepping mode again as was described earlier. note : in during of changing the reset level from low to high the in1 (in2) level must be high. please, for more detail des cription of operation see the section timing diagram .
