 Example
【Function】
The figure shown below is electronic cam data.
Electronic cam cycle: Master position 0~100000
Control unit: Motor system
Every time when START0 is triggered, execute 3 noncyclic electronic cam data (D1832=2)
In this example, the electronic cam data is created by PMSoft. Please refer to section 9.4 for more
information about creating electronic cam data. Connect the Y-axis pulse output terminals (FP+, FP-,
RP+, RP-) to the X-axis MPG input terminals (A0+, A0-, B0+, B0-). In this case, the input signals of
the master axis are from output signals of the Y-axis.
【Steps】
1. Set special registers. The parameters set are as follows.
(1) Clear the content in registers D1848, D1849, D1862, D1863, D1868.
(2) Set up input pulse type as A/B phase (D1864=H200).
(3) Set up pulse output type of Y axis as A/B phase (D1896=H30)
(4) Set up D1799 (input terminal polarity setting)=6, MPGA0 and MPGB0 are NO contacts.
(5) Set M1035=ON to enable STOP0/START0 as external input point.
(6) Set M1746=OFF to enable START0 as the start signal of noncyclic electronic cam.
