Hi to everyone,
Today i was starting an application with my customer and we encountered a problem. The device situation is the following:
ctrlX works 1.12.3.
If we try to read the velocity of a real axis we have no feedback. In other hands the FB is working perfectly with a virtual axis.
Do you know what can have we done wrong? This is the fist time i encounter this problem.
Thanks
Mauro
Solved! Go to Solution.

Hello Mauro
Please take a look at this threat:

Hello,
I am the customer developing the application.
As I read in the suggested thread, I added the velocity and torque feedback to the variables in AT in the CtrlX IO Engineering.
Then I can see the variables in the Data Layer in the PLC
However I still don't see the velocity varying from 0. I tried both linking a plc variable to the object in the datalayer both with the MC_ReadActualVelocity function block.
In the web interface/Axis profile, I can now see the feedbacks but I don't have where to map them
Thank you,
Giacomo

Hello
Motion App Version 1.12
You are using the Version 1.12. Here the Motion don't support the Veloctiy Mode. So you don't have the possibilities to map the veloctiy at the axis profile.
-> The PLC open FB MC_ReadActualVelocity don't gives you any velocity data from the real drive (virtual it is working)
The only possiblity to get the drive veloctiy at the PLC, you have to map the value at the DataLayer_Realtime inside the PLC-Engineering. -> see Screenshot. Here I make a global variable mapped to the AT.Velocity_feedback_value_of_encoder_1. You see the Value 91552 = 9,1552 RPM (DINT value)
notes:
Motion App Version 1.14 and higher
Beside the upper descripted way, in the version 1.14 (or higher) the Motion App supports the velocity mode. Means it is possible to map it at the AxisProfile. Then the motion get's knowledge about the actual drive velocity and can be read vie the plcopen FB.

Thank you for your precise answer.
We tested the velocity and we can now update correctly the velocity in exchange with Ethercat with Version 1.12.
Is there a way to update to 1.14? In the App section of the ctrlX web Interface I don't see any App with available updates and the version in the app store is 1.12.
Thank you

Hi,
First of all thanks for the availability @Jochen_Mueller . Happy that it was not our misconf but just a "missing" feature in 1.12.
Till now we will manage to get the velocity using the readParameter function. (see Read Params thread).
Thanks
Mauro

It would be actually interesting to know where to get version 1.14 of the motion app, if using 1.14 is the solution to the problem of getting the velocity.

The version 1.14 is out of support. Currently you will have to use version 1.18 that can be found in the collaboration room for approved customers. Get in contact with your know sales person from Bosch Rexroth to get access.
