The function of reading electronic cam status in capture mode should be used with M1757 (Remain
current speed), and can be applied for checking the cutter position in flying shear applications. For
details please refer to 9.4.2.6.
9.4.2.1 Creating/Modifying Electronic Cam Data
After users create electronic cam data in a cam chart in PMSoft, the cam data will be downloaded to a
DVP-20PM series motion controller. If the users modify the electronic cam data in PMSoft, they have to
download the new electronic cam data created to the DVP-20PM series motion controller again after
they modify the electronic cam data. A DVP-20PM series motion controller allow users to modify
electronic cam data. The users can modify electronic cam data when the program in the DVP-20PM
series motion controller is executed.
Data length of electronic cam data can be real-time modified. When 4 words of one point (set) of
electronic cam data are all 0 and identified, DVP-20PM will take it as electronic cam completion.
Therefore, if users want to modify 10 points electronic cam data into 5 points, DTO instruction can be
applied to write 0 into the 4 words of the sixth point.
