I use B&R Automation Studio 3.0.90, their PLC X20CP1485-1 and stepper drive module X67SM2436. ACP10 library. I need to rotate stepper motor only clockwise (process demands it). On the other hand I need coordinate was only in 0-360 rang and do not grow infinitely. What should I do?

I switch to module of third-party brand due to another problem [image] X67 module error Mechatronics & Motion The problem was with X67SM2436 and encoder (I suppose it was noise in power bus). I didn’t find out solution so just replace X67SM2436 to module of ano…

Hi, I haven’t any experience with axes programming, but when using ACP10 I think you could have a look here how to setup periodic axes: https://help.br-automation.com/#/en/6/libraries%2Facp10_mc%2Fkonzept%2Fachsperiode.html Best regards!

For ACP10, you will need to use the Smart Device Controller ( ACP10SDC ) functionality so that ACP10 can control the non-servo axis. (If you aren’t using any feedback on B&Rmotors (SSI, ABR, Hiperface), but internal step count, they have 1.8 degree steps. With the X67SM2436 capable of 256 microsteps,…

Thank you for the answer! However, how can I set the axis as periodic in the mapping table via the additional information? I can’t find any information about configuring Additional Data column in mapping table. I used it to link a software axis to its hardware interface variable. I would be very g…

PLCopen_ModPos=“,” See Axis Factor in AS4 Help: Axis factor [image]

I believe you can use the comma to separate multiple arguments, so it would look like PLCopen_ModPos=”3600,1”, SDC_AX_HwPv=“gSDCAx1” If this isn’t working (as I don’t have hardware to test this on at the moment), I would recommend using the MC_BR_InitModPos. I generally recommend defining things …

Hi @Sergey_Kashchuk , have you found solution for your issue? can you share it with us?

ok I marked your temporary solution as a possible solution for now. thanks for update

Temporary I am using axe as infinite linear. It isn’t a solution but it is OK for now. I’ll return to this problem at the end of commissioning.
