The circumference of a slave axis specified is the number of pulses it takes for the slave
axis to rotate once. In this example, the circumference of the slave axis specified is 10,000
pulses.

The distance for which a slave axis is synchronized with a master axis is thirty percent of the
circumference of the slave axis.

Calculating a synchronization ratio

The circumference of the master axis specified is 314 mm.

The number of pulses it takes for the master axis specified to rotate once is 10,000.

The circumference of the slave axis specified is 188 mm.

The number of pulses it takes for the slave axis specified to rotate once is 10,000.

Maximum ratio of the speed of the slave axis specified to the speed of the master axis
specified: Ten times the synchronization ratio of the speed of the slave axis specified to the
speed of the master axis specified.

Acceleration curve: Uniform curve

Rotary cut curve: rightCAM

The Concatenate input pin is set to False.
After the input pins in the motion control function block T_CamCurve are set in accordance with
the setting described above, a cam curve can be created.
