Normalization of phys. units of machine data and setting data

Standard
Machine and setting data having a physical unit are interpreted in the input/output units listed
in the table "Scaling physical units of machine and setting data" by default, depending on the
scaling system (metric/inch).
The internally used units which the NC uses are independent and fixed.

User-defined
The user can define different input/output units for machine and setting data.
For this purpose,
• MD10220 SCALING_USER_DEF_MASK (activation of scaling factors) and
• MD10230 SCALING_FACTORS_USER_DEF[n] (scaling factors of the physical
allow you to set the adaptation between the newly selected input/output units and the
internal units.
