This will depend on the switch setting:
Look on page 25 - Setting the Modbus Plus Node Address

Communicate with modbus directly

I want to communicate with modbus rtu to vlt 5000 directly not using modbus plus option card

Have you tried actually looking on the Danfoss website and reading the manuals? I am pretty sure it's there.

Well since this is a legacy drive you will have to visit here:

http://vltdrives.danfoss.us/products/tools/legacy-manuals/
to find the manuals, and mind you not all are there!
I was not able to find the ModbusRTU manual there, but I did fine one:

http://www.fbk.com.tw/file/serial%20report/VLT%205000%20Modbus%20RTU%20Manual.pdf
But again it is not a build in ModbusRTU, but rather an option card - I have not been able to find out if it actually was build in.

If this is a new project I would strongly suggest you to switch to the newer FC302 series drives, as you will not be able to buy new VLT5000 anymore, and the spareparts are not going to be available for too many years either.
