2.1.6 Scaling of physical quantities of machine and setting data
Input/output units
Machine and setting data that possess a physical quantity are interpreted in the input/output
units below depending on whether the metric or inch system is 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 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.
