Hi!, I have an inverter that the power section definition isnt correct, P070,  if I change it, do I loose the actual parametrization?

Hi, the fact that p72 does not download, tells me that you did not pay attention to the posts on the previous thread.

You MUST perform the "Power section definition", otherwise you can cause damage to your inverter - see the Compendium, in the version I have, this is section 6.3.1.

After this is complete, then you can download your own parameters.

Split from Masterdrive, can't download all Parameters with Drive Monitor..

Hello,

Yes. Before you change or correct power section parameter, take the back up of existing parameter. Correct the power section by entering correct parameter & then reload the back up you have.

 HTH.

 thankyou PISCEAN 2010 for your prompt response , but I have a doubt , it is normal that this parameterization , P070 , miss ? Considering that the PMU is blocked .... thanks a gain 

What do you mean by parameter block?

Are you not able to view P070 in PMU?

What is the value in P060?

Please refer the attached sheet for more information. Depending upon user requirement P060 is programed so that parameter values could be accessed more easily.

HTH.

 ok I cant make any change in any parameter, I have access to all parameter but cant change

Yes, I can view the P070 in PMU, the inverter is 6SE7031-0TE60, the PWE for this inverter is 75 (Im not shure) but in P070 it is 18 right now.

the P060 is programed in 7

this machine was working on another site and move it , when reconnecting indicates a F011 fails to check me indicates that there may be a mismatch between drive and engine , checking then I find that the P070 is in value 18

How much is the value in P071 & P072?

Hello,

This is chassis type inverter unit. DC voltage range is 510-650 V DC. Output 92 A.

Please provide the input & out put motor details.

How much is the value in P071 & P072?

 P071 is on 600 V

P072 is on 92 A

the motor details are

390 V

75.2 A

60 hp

What is the input side? Is it converter / rectifier ? Provide detail MLFB.

 about the input side, there is a rectifier, on the electrical panel, this provide the DC input to the inverter, I have not much more detail about the MLFB, only the following
