Hello, I have a misunderstanding about Profibus telegrams between G120 (starter) and S7-400

The words sent from the VFD to PLC as like (Actual speed, torque actual value, status words ….etc)

I want to know,what is the units of these words by default?is by percentage (%) or by real unit like (Rpm, Nm, Volts…etc)

For my case I wants the value to be sent by percentage relatively to parameter P2000, P2001, P2002, P2003

But I want to be sure if:

• Is it by default, program send the value in real value (Rpm, Nm, Volts…etc) and I should activate another parameter to make it send the values by percentage?
• Or is it by defaults send the output of G120 scaled automatically with default value of P2000, P2001, P2002, and the output value are in percentage?

Thank you
