4.4.5 Operation Check 4: Phase Control - Electronic Cam
( 1 ) Machine Outline
As shown in the following figure, the Servomotor performs the same operation as the mechanical cam synchronized to
a roller connected to the line shaft. No phase matching is used.
( 2 ) Program Overview
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).
Refer to
4.4.5 ( 5 ) Sample Program Details
on page 4-64 for details of H06.01 Drawing.
A simple device is used in this example to describe the MP2300 system startup. Caution is required because actual
applications will be different.
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.
