The units listed below are used for storage. The control always uses these units internally irrespective of the
basic system selected.
Physical quantity:
Linear position
Angular position
Linear velocity
Angular velocity
Linear acceleration
Angular acceleration
Linear jerk
Angular jerk
Time
Position controller servo gain
Rev. feedrate
Compensation value linear position
Compensation value angular position
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.
