5 Applied Instructions and Basic Usage
Using T_CamCurveUpdate and T_CamCurve
If users create a new cam curve by means of the motion control function block T_CamCurve when the
slave axis specified meshes with the master axis specified, and want to update the cam chart selected
by means of a condition instead of updating the cam chart selected immediately, they can use the
motion control function block T_CamCurveUpdate.

Using T_CamCurveUpdate and T_CamWrite
If users use the motion control function block T_CamWrite to modify a point in the cam chart selected
when the slave axis specified meshes with the master axis specified, the cam chart selected will not
change after the point is modified. After the users update the cam chart selected by means of the
motion control function block T_CamCurveUpdate, the cam chart created after the motion control
function block T_CamWrite is used will be executed.

3. Troubleshooting
Error Troubleshooting
The values of input pins in the motion control function
block are incorrect.
Check whether the values of the input pins are in the
ranges allowed.
4. Modules which are supported
The motion control function block T_CamCurveUpdate supports DVP20PM00D and DVP20PM00M.
