Can anyone tell if it would be possible to make a PLC program, that could send setup using powerlink to a VFD and then change the setup (command channel) in VFD so it uses I/O and would run as a standalone? This is for using B&R VFD to retrofit standalone non B&R inverters and not have to run the …

Hello Claus, coming in from ACOPOSinverter development: You can definitely achieve your idea, no problem. First you are not removing Powerlink, you are just switching the reference and control words away from the Powerlink-master to your I/O control. So the thing you have to do is: Make a task t…

Hi @Claus_Lind , to be honest doesn’t look like a cheap solution. You buy VFDs and you install the powerlink inteface card (in all of them) just for commissioning? For what you have described the B&R VFD is not totally integrated on their machine, so when the VFD is in error, for example you have …

Hello Claus, to add some things to Valerio’s information regarding the implementation → you should look into the AsEPL library. With that library you can read and write Powerlink registers. The necessary index and subindex are described in the documentation of the specific VFD. As far as I know,…

Hello Claus, If you are using the ACOPOSInverter P77, you can find a list of the parameters at the end of the Commissioning Handbook. There, you can find the data type and length for the index and subindex. Depending on the number of parameters you have to change, a keypad for the P77 could also be…

Thanks @alexanderstieglbauer , I think we have few libraries developed in different B&R offices for downloading all powerlink parameters online, and some customers have developed similar by their self, BUT in all cases (as far as I know) the B&R CPU is connected to the B&R powerlink VFD all the tim…

First of all, thank you for all your replies. This will mainly concern P66 and P86. The replacements are older (KEB, Vectron) inverters. Pure I/O - 0-10V or similar is used. We are making this change worldwide as spare part upgrades. To ensure that the correct parameters are entered into the in…

Hi Claus, I don’t think you can completely remove the connection to powerlink via powerlink. Few notes I have found in the ACOPOSinverter P66 User’s manual : Network fault mgt: theoretically you can ignore network fault (not recommended, but necessary in your case) [image] Not sure the react…

Hello Valerio, you have some great and valid points here although they do not apply in this case because: After disconnecting and using the device standalone there is no Powerlink connection established and therefore never a network loss fault. The drive is actually not in fault as stated in 1. T…
