The scaling of machine data having physical units is defined by the following
machine data:
S
MD 10220: SCALING_USER_DEF_MASK (activation of scaling factors)
S
MD 10230: SCALING_FACTORS_USER_DEF (scaling factors of physical
quantities)
S
MD 10240: SCALING_SYSTEM_IS_METRIC (basic system metric)
S
MD 10250: SCALING_VALUE_INCH (conversion factor for switchover to
INCH system)
S
MD 30300: IS_ROT_AX (rotary axis)
When scaling machine data are modified, all machine data affected by this mod-
ification due to their physical unit are converted with the next NCK reset.
Example: Redefining an A1 axis from linear to rotary axis.
