Main drive
The main computer has two versions:
JD Main computer FD is equipped with frequency inverters. These control the speed of the machine. The drives have built-in security and are connected to the security CPU of the JD operating system.
JD Main-Drive SD is equipped with servo drives. Each section will be equipped with one or more servo drives. These drives control the speed of the machine and the position of the boxes in all sections. When an error is detected (see also JD Jam detection and JD Glue detection), the machine is switched off section by section. This results in less waste. Especially when hot-melt glue is used.
The drives have built-in security and are connected to the security CPU of the JD operating system.
