Hi all

i am trying to use motion control with a Hydraulic valve on an analogue output and data block using telegram 83 in TIA14 

does anyone know how to use the axis tuning facility ? to set the gain and precontrol values

also what does the precontrol value do ? and how can you set it and the gain KV from a HMI if possible

also when  using telegram 83 from a data block i have issues with Gx_XIST1 and Gx_XIST2 when the TO switches on  the second value they both read reading the same value and the axis errors

Regards

Mel
