【Control program】
1. Using the motion control function block T_CamCurve to automatically create an electronic cam
curve

Users have to set the length of a cutting. The length of a cutting is 500 mm.

500 mm

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.
2. Main program in PMSoft
【Steps】
1. Open a CAM Chart window in PMSoft, and then type 300 in the Resolution box.
2. Download the program created to an AH500 series motion control module, and then execute the
program.
