2 Functions of Devices in DVP-PLC Step 2: Calculate the distance (number of pulses) between every section In X axis: x 1 = x 1 – 0, x 2 = x 2 – x 1 , ... x 10 = x 10 – x 9 (see Table 5) In Y axis: y 1 = y 1 – 0, y 2 = y 2 – y 1 , … y 10 = y 10 – y 9 (see Table 5) (Table 5) Step 3: Decide the execution time of every section and obtain the frequency of every section by Table 5 x1 、 fx 2 =1ч0.5 Ч x 2 …(see Table 6) Assume every section executes for 500ms, the equation for frequency (Hz) of each section is: fx 1 = 1ч0.5 Ч (Table 6) Step 4: Fill Device D into table 2 and complete all steps. Reminder 1:
When Rx=Ry, you can calculate X axis, and copy X axis to Y axis (as fy1 = fx10, fy2 = fx9, …fy10 = fx1, and y1 = x10, y2 = x9,…y10 = x1 ) Reminder 2: When drawing a counterclockwise arc, switch the index value of X axis with that of Y axis.
