DEAR SIR, FOR 

 WE NEED SUPPORT FOR KINETIC ENERGY SOLUTION IN SINAMICS G120 PM240-2 DRIVE SYSTEM WITH CU 240E- 2 PN.

Hello,

would you please specify your requirements and application for everyone here in the forum? 

It is not really clear what you are looking for. The G120 has some features that deal with the kinetic energy of the driven motor / load, such as the Vdc min and Vdc max control which are used to protect the drive from undervoltage or overvoltage. But absolutely not sure for what you are looking. Is it about a software feature or do you need tips for hardware sizing?
