User-defined
The user can define different input/output units for machine and setting data.
For this there must be an adjustment between the newly selected input/output units and the
internal units via the following MD:
●
MD10220 $MN_SCALING_USER_DEF_MASK (activation of standardizing factors) and
●
MD10230 $MN_SCALING_FACTORS_USER_DEF[n] (standardizing factors of the
physical quantities)

The following applies:
Selected I/O unit =
MD10230 $MN_SCALING_FACTORS_USER_DEF[n] * internal unit
The selected I/O unit, expressed in the internal units 1 mm, 1 degree and 1 s must therefore
be entered in MD10230 $MN_SCALING_FACTORS_USER_DEF[n].
