Machine and setting data having a physical unit are interpreted in the input/
output units listed in Table 11-6 by default, depending on the scaling system
(metric/inch).
The internally used units which the NCK uses are independent and fixed.

The user can define different input/output units for machine and setting data.
For this purpose,
S
MD 10220: SCALING_USER_DEF_MASK (activation of scaling factors) and
S
MD 10230: SCALING_FACTORS_USER_DEF[n] (scaling factors of the
physical quantities)
allow you to set the adaptation between the newly selected input/output units
and the internal units.
