P77 not recognized by EASY starter

Ask Questions Mechatronics & Motion

Hello,
Just started testing the P77 inverter and found that the EASY Starter software used for inverter commissioning does not recognize it. I am using version 1.29, which I have previously used successfully with i550 inverters.

EASY Starter is mentioned several times in the P77 commissioning manual, but I am not sure whether there is a dedicated version for B&R.

Does anyone have experience with commissioning the P77 inverter?

Thank you.

Hi @Michal_Malek
While EASY Starter is typically a Lenze engineering tool, the ACOPOSinverter P77 is fully integrated into our Automation Studio.
Our knowledge is more focus on the usage of that with Automation Studio.

For compatibility questions with Lenze tool I think the better channel is the local B&R Support, they can create a CASE and ask R&D more details.

Hi Valerio,
You are certainly right that for most applications, the integrated capabilities are sufficient. However, sometimes you need to make measurements, check some internal variables, parameters, or implement features not included within the P77 configuration parameters in AS. In fact, the majority of my applications require this.

Yes, you can buy a LENZE product directly, but it makes no sense when you already have it within reach. With Px6, you can use all Schneider tools, so I hope this is the case here as well.

Thank you.

Hi Michael,
I think there is a misunderstanding, sorry about that.
I downloaded the documentation of P77 from our website and in one pdf , Commissioning_ACOPOSinverter_P77_ENG.pdf, as you said in few sections it describes “EASY Starter”.
Unfortunately in the document there is no link to “EASY Starter”, so I said to myself: “What is this EASY Starter?”.
I tried to download it from our download page and I did find that so I asked AI and it pointed me to Lenze website.
From Lenze website I read since version 1.28 “EASY Starter” is free of charge, that is good.
At the end I thought, ok someone from R&D wrote that pdf so R&D should have more information than Community about that sw.

However, sometimes you need to make measurements, check some internal variables, parameters, or implement features not included within the P77 configuration parameters in AS. In fact, the majority of my applications require this.

Good to know, please share with us the features not included in the P77 configuration; when you buy a product you would like to access to all of them…hehe.

Hi Valerio,
I’m using the latest version (1.29) of EASY Starter (ES), but it seems that you need to upload a package related to P77. For LENZE, it looks like this:

At the bottom, there is a link to the package source, and I assume that some B&R link should be added there, but I might be wrong.
Regarding features:

  • First of all, the available monitoring data points are quite odd }(ou would need a very specific application to make use of quantities like q- and d-axis currents), and there are only a few of them. So as a first “feature,” you basically need to read them via the application.
  • There is also the 0x400A process status word, which you can use instead of some missing data points. However, it is not available as a word but only as individual bits (in I/O mapping). Most of them are quite unusual again. I can imagine they are intended for use in the prepared McAcpInvAx, but for basic applications it is better to use it as a configurable word, which then takes up space in ES.
  • The most important feature, in my opinion, is the autotuning procedure, which seems to be missing. You can call it via SDO or again use ES during the initial commissioning.
  • I also have applications with several motors and only a single inverter, so it is necessary to switch between parameter sets. Again, this can be configured and controlled via the application, or set during the initial commissioning in ES.

Thank you

Thanks Michal for your information!
Now you make me curious and I’ll ask our Support more details.

Hi Valerio,
finally, I have received a release of the installation package for the device description file (.lpk; 08/2025):

Therefore, the issue can now be considered resolved.
I am not sure whether this is an official or development version, nor whether it is appropriate to share it here.
Thank you for your support.
