PROTECTION OF CNC MACHINES AGAINST SUDDEN OVERVOLTAGES

CNC machines are machines of vital importance for an industrial facility. Damage to the machine mainboard and PLC system as a result of a transient overvoltage surge will both prevent sustainable production and create serious costs due to replaced machine components. Especially in devices controlled by variable frequency drives, problems caused by transient overvoltage are frequently observed.

In modern CNC machines, manual control has now completely given way to embedded software and automation control. To keep this system under control, variable frequency drives, servo motors, and motion control systems are included in this machine system. All of these systems are very easily affected by possible transient overvoltage and lightning surges, and board failures occur frequently.

A manufacturer must protect CNC machines against lightning and transient surges. While doing so, as Yılkomer, we recommend protection with Strikesorb LV Surge Arrester systems with a 10-year product warranty.

Within the scope of IEC 61643-11, by providing Type 1 and Type 2 protection on CNC systems, we protect the machine against possible surges. In the Strikesorb system, no pre-protection fuse is required and it can be integrated directly inline into the system. All harmful surges reaching the machine are detected within 1 ns and are suppressed by Strikesorb. The stable voltage level provided by Raycap Strikesorb prevents damage to the boards. You can see a typical variable frequency drive application in Figure 1.

If we focus on the benefits of the Strikesorb System for CNC systems;

-Provides protection without requiring any maintenance.
-Ensures safe operation. There is no risk of smoke, arc, or explosion.
-Can suppress a large number of surges; it is not single-use.
-When compared with competing products, it has the lowest Up level. It provides excellent protection.
-Compliant with Class 1 and Class 2 within the scope of IEC 61643-11.
-Compliant with UL 1449. Provides Type 4 protection.
-Offers a 10-year product warranty and unlimited replacement warranty. If the product is damaged in any way within 10 years, it is replaced an unlimited number of times.

Strikesorb systems protect machines in hundreds of thousands of facilities worldwide. You can contact Yılkomer’s expert team regarding the integration of Strikesorb systems into CNC systems.
