Hi,
Level 4 parameters are factory parameters and are password protected. What is the reason you need to access these parameters?

What about that:

Measuring and entering the magnetizing current and therefore the associated new calculation of the equivalent circuit diagram data of the motor is an iterative procedure. It must be repeated at least 2-3 times until the following criteriaare fulfilled:

−The more accurate the value of the magnetizing current that was entered, the better theflux setpoint (r1598=100%)matches the flux actual value (r0084=96..104%)of the observer model.

−Theoutput Xm adaptation (r1787)of the observer model should be as low as possible. Good values lie between1-5%.The less that the Xh adaptation of the observer must operate, the sensitivity of the motor parameters after power failures are that much less sensitive.

NOTE

In order to display r0084 at the BOP/AOP, the LEVEL 4 parameters must be enabled using service parameter P3950=46.
