SINUMERIK 840Di Manual (HBI) – 06.03 Edition
Machine and setting data having a physical unit are interpreted in the input/out-
put units listed in Table 10-6 by default, depending on the scaling system (met-
ric/inch).
The internally used units which the NC uses are independent and fixed.

The user can define different input/output units for machine and setting data.
To this aim, an adaptation between newly selected input/output units and the
internal units must be made in
S
MD 10220: SCALING_USER_DEF_MASK (activation of scaling factors) and
S
MD 10230: SCALING_FACTORS_USER_DEF[n] (scaling factors of physi-
cal quantities)
.
