Hi expert,
I tried to get some help from the seimens support but looks like its a long process and I want some urgent help.I also found that you are too good with this stuff so decided to ask help this way directly.Please help me if you can asap.

I am new to these drives and also just joined back on duty and facing this problem.We have 3 MICROMASTER 440 units installed on separate systems. One of them has started to stop/trip showing-- Tripped F003 [2] -Under voltage. On restarting it worked well. But it trips quite often with the same fault. We would like to see the value setting on the parameter P0210 but its impossible to see it because when we go through the Menu on the AOP and select parameters, it it changes to –r0000 and when we press UP or DOWN it starts searching and returns back to the same –r0000.
Looks like the Parameter Access Level is altered or something. So if we have no access to get to the parameter P0003 we can not change the level of access.
Please let us know -HOW WE CAN GET ACCESS TO SEE AND MODIFY ANY PARAMETER?

Another issue is--
When we go through the menu and select MODE to -- LOCAL MODE and acknowledge with-"P", the display show a message-- P-----( Lost).

Any help will be really appreciated.

Best regards

Francis
