After repairing the machine (and possibly replacing the module) I have ACOPOS error code 6057 and 21221. What could it be? Even if there is no clear answer, please share ideas. It may help me..
CPU X20CP1485-1 and X67SM2436.
Thanks in advance.
Just a general idea of where to start: if you are not sure if the hardware (HW) state is correct, please use the system diagnostic manager to check the status of your complete HW configuration. Additionally, the logger can provide you with a basic overview of possible problems.

you can also use conversational help. B&R Online Help and ask for some hints, this can also help. Please we aware that AI generated answer can be wrong 
so basic technical user knowledge is needed

Hi,
I would check first the led status of the X67 module. It could be a wrong wiring.
As @kovarj said check the SDM for maybe other module error and the logger for details informations.

Hello,
The Error Code 6057 can be checked in AS-Help. (see Picture)
It indicates an Error on the Encoder connected to the Axis.
Based on the fact that your Screenshots and Ordernumber advise that it is a Steppermodule you are diagnosing. You may check this diagram for wireing.
The module normaly indicates this error via EncOk01 for Axis 1 and EncOk02 for Axis 2
You did indicate that you do not have the software running on the plc (in another thread). This limits the possibilitys drasticaly as you would not be able to make a transfer of changed settings. You have to trust that the program and settings on the plc are correct to drive the motor.

Is it possible that this error is caused by the wrong version of the X67SM2436 module (which I use for the stepper motor)? I mean, there is not only a part number on the module, but also a version number (e.g. ver. H0, ver. P9). I am not on the site right now and do not remember the version. However, could this be the problem?
Hello,
The Revision Number (e.g. ver. H0, ver. P9) is used to mark different Hardware implementations of the Module (eg. change of a Resistor supplier). If the module has the same Productnumber it is meant to be compatible without restrictions. But in very rare edge cases a different Revision can cause issues, for example if the application was slightly out side of spec and was only lucky to work with a special Revision, but with an other one it doesn’t.
If a module as known compatibility issues B&R adds a -1 to the Productnumber to alter the number and symbolise the limited incombatibility.
The Revision can be read via SDM if a remote connection is available.

It is possible but not intended.
If you have multiple Modules in the Machine a switch between a working and not working one would give additional information about this topic.

We replace X67SM2436 to new ones. Also, we have replaced: wires, encoders, stepper motors. However, errors persist.

Good day, we have the same problem and the same errors. I would like to know if you managed to fix them?
Unfortunately, didn’t…

IIf it works out, let me know. And the same will happen from my side.
Hello,
as this seems to be a hard to diagnose error from the distance and the documentation about the error number hinting to the encoder did not help you. You could get in contact with a local B&R support and disscuss possible further options.
Also contacting the machine manufacturer would be a idea. As we can now see that more than one machine of this manufacturer is having the issue.
Sorry that i can’t provide you more ideas from the distance.
Feel free to continue the discussion here.
Greetings
Michael
