The following shows an operation overview of the FBs.
At the startup, use M+CamCtr_CamOutputTable (Cam output table setting) and M+CamCtr_AngleAdvFunc (Automatic angle
advance function setting) and set each cam output data of the global label.
In normal use, the cam output is performed every 1 ms according to the setting data of the global label by turning on the
execution command of M+CamCtr_CamOutput (Cam output).
When using this FB library, set the program capacity of the CPU parameter to 64000 steps.
If it is set to 128000 steps, the operation may not be performed normally.
• Cam output table setting
This FB is executed in the scan processing when the cam output table is set.
(When table data set is off)
1. By turning on i_bEN (Execution command), the synchronization flag of the global label is turned on and becomes read
protected.
2. The rotation direction, resolution, and control angle data for the input corresponding to the input channel number and the
cam output data of the cap output number are stored in the global label.
3. By turning off i_bEN (Execution command), the synchronization flag of the global label is turned off and reading is
enabled.
(When table data set is on)
4. By turning on i_bEN (Execution command), the synchronization flag of the global label is turned on and becomes read
protected.
5. The cam output data is set according to the control angle data of all global labels.
6. By turning off i_bEN (Execution command), the synchronization flag of the global label is turned off and reading is
enabled.

• Automatic angle advance function setting FB
This FB is executed in the scan processing when the angle advance function is set.
7. By turning on i_bEN (Execution command), the synchronization flag of the global label is turned on and becomes read
protected.
8. The angle advance function setting and angle advance function selection for the input corresponding to the input channel
number are stored in the global label.
9. By turning off i_bEN (Execution command), the synchronization flag of the global label is turned off and reading is
enabled.
• Cam output FB
The cam output is executed in 1 ms cycles.
10. While the synchronization flag of the global label is on, the response from the cam output is delayed.
11. By turning on i_bEN (Execution command), the cam output is executed according to data of the rotation direction,
resolution, cam output data, angle advance function selection, and angle advance function setting for the global label
corresponding to the input channel number.
