Description
Normally, the built-in backlight brightness to be used for a part is set in the Part Feeding Configuration dialog. If changes to brightness are required at runtime, you can use this command to change it.
This function cannot be executed from the command window.
The backlight brightness is not changed in the virtual controller.

KEY POINTS

---

The brightness can be set as a percentage in the range of 0 to 100%, but for IF-240, the actual minimum brightness will be limited to 25%, even if you set the brightness below 25%. This is because uniform brightness cannot be obtained below a certain degree.

If you would like 0% backlight brightness, use the PF_Backlight statement to turn off the backlight.

Examples
