[Max1]

Hello Rexroth Team

I have a question,When I use the "MC_ReadActualVelocity" FB to read Axis Velocity,I can't see any value?

I have add S-0-0040 in ctrlx IO Software and Download it ,but I also can't add the velocity feed back value in the axis profile?

Does anybody know how to solved this issus?

Please see the CtrlXWorks Version(ctrlX WORKS WRK-V-0114.1) ,APP Version and Core Information from the attached picture.

Hello Max

Your are using ctrlX WORKS V1.14, that's right. But you use the motion app 1.12.x. To use the way described at this threat  https://developer.community.boschrexroth.com/t5/ctrlX-MOTION/No-Velocity-feedback-Motion-PLC/m-p/653... you still have to update the complete ctrlX CORE (system apps + functional apps (including motion app) to version 1.14 or higher.
