How to use the RVEL field of the motor record

["Mathis, Stefan via Tech-talk" <tech-talk at aps.anl.gov>]

Dear all,

I have a asynMotor-based driver (controller inherits from asynMotorController and axis inherits from asynMotorAxis). I would like to populate the RVEL field with the actual velocity read from the hardware, but can't get it to work.

From looking through the source code of the motor record, it seems that the param-lib entry with the index motorVelocity_  is involved into populating RVEL. However, just writing to this param-lib entry and then running callParamCallbacks() does not seem to be sufficient. Are there any other param-lib entries which influence this?

Is there any asynMotor-based example where the RVEL field is actually used?

Thank you very much

Stefan
