Hello,

what signals do you use for trace?

I thought, the signal units of the technology object "PositionAxis" are like this:

• <Axis>.ActualSpeed = Actual motor speed in rpm
• <Axis>.position and <Axis>.ActualPosition = SetValue/ActualValue of axis position in mm or ° (in your case) - as units are set at the technology object.
• <Axis>.velocity and <Axis>.ActualVelocity = SetValue/ActualValue of axis velocity in mm/s or °/s (in your case) - as units are set at the technology object.

Using the trace - see "Signal tab":

• You could define "scaling groups" via name, for example "v" for velocity and "p" for position and define "Min. Y scale" and "Max. Y scale" for trace presentation.
  With this, you could set all velocity signals to the same scaling by selecting the same sacling group for each velocity signal and so on...
  
  
• With the eye-symbol (second column), you could show and hide the signals in the graphics.
