8.3.1.3 Creating/Modifying Electronic Cam Data
After users create electronic cam data in a cam chart in PMSoft, the cam data will be downloaded to
an AH500 series motion control module. If the users modify the electronic cam data in PMSoft, they
have to download the new electronic cam data created to the AH500 series motion control module
again after they modify the electronic cam data. If the users want to modify the electronic cam data
in the program in the AH500 series motion control module, they can use motion control function
blocks.
The motion control function block T_CamRead is used to read a particular point in a cam chart, and
the motion control function block T_CamWrite is used to modify a particular point in a cam chart.
