SERCOS drives have the ability to have configurable levels of precision (number of decimal places) for each type of parameter, depending on the parameters units, i.e. velocity units.

The XL needs to know the precision of the units in order to correctly interact with the drive and scale the value it sends and receives from the drive.

The XL has always set the precision of the velocity units for example so that they would be in a consistent known format.

A tech in the field experienced an issue where the chosen precision was limiting the speed that could be used by the Axis. The motor was capable of running faster but the precision of the velocity units places an upper limit on how fast the drive would run the axis.

In order to allow the precision to be changed to suit the techs installation without affecting legacy installs, the XL software was modified to read the precision setting out of the drive and to use it to do its conversions rather than set the precision. This was only done for Multi-Axis drives. Feeder and DA drives still function and use the precision configured by the XL.
