(2) Program Outline
Use the ladder program (H06.02 Drawing) to check the above operation.
The two axes rotate synchronized with the input speed setting. Axis 1 is the roll axis (Master axis) and axis 2 is
the cam axis (Slave axis, which moves in COS cam pattern against Master axis).
Cam pattern data is created using a ladder program (L06 Drawing).
Note: 1. Refer to 4.4.5 (5) Sample Program Details for details of H06.02 Drawing.
2. A simple device is used in this example to describe the MP2100 system startup. Caution is required because
actual applications will be different.
3. This device has no power OFF circuit for the SERVOPACK in the event of emergency stops or overtravel.
Include a proper emergency stop circuit in actual applications.
