The units listed below are used for storage. The control always uses these units internally irrespective of the
basic system selected.
The user can define different input/output units for machine and setting data.
For this, the machine data:
MD10220 $MN_SCALING_USER_DEF_MASK
(activation of scaling factors)
and
MD10230 $MN_SCALING_FACTORS_USER_DEF[n]
(Scaling factors of physical quantities)
allow you to set the adaptation between the newly selected input/output units and the internal units.
