If you are using Sinamics Starter to commission the VFD(s), you can easily modify the telegram.

However, in the interest of saving you a lot of headache, I recommend configuring your VFD first with telegram 352. Once that is done and the PLC and VFD are communicating correctly, modify the telegram in the VFD using Starter to Free Telegram 12/12.

Then you can modify the newly added telegram words (leaving the existing and working Telegram 352 parameters alone) to whatever parameters you wish.  Keep in mind, Telegram 352 will give you motor current and torque built into that telegram, so you would only need to add power and voltage.

Keep in mind you also need to set the proper 100% reference values in the VFD (p200n's) and use those to rescale the -27648 to +27648 data coming from the VFD for current, torque, power, and voltage.

There are many forum posts and online FAQs and manuals discussing this at length.
