Cam Position Calculation Function - Mitsubishi Electric QD77MS User Manual

5.5 Cam position calculation function

The cam position is calculated by the program with this function. This function can be used to
calculate the cam position for the synchronous control initial position before starting
synchronous control.
Example
The following shows the procedure for synchronous position alignment, in a synchronous
system where cam axes 2 and 3 are synchronized with the cam axis current value per
cycle of axis 1.
1) Calculate the cam axis current value per cycle using this function based on the feed
2) Calculate the cam axis feed current value of axis 2 with this function based on the cam
3) Calculate the cam axis feed current value of axis 3 with this function based on the cam
4) Execute positioning on axis 2 to the cam axis feed current value which was calculated
5) Start synchronous control on axis 1, 2 and 3 with the feed current value restoration

mode. Use the cam axis current value per cycle that was calculated in 1) for the cam
axis current value per cycle (Initial setting).
