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: Input/output units for standard basic system:
Metric Inch
Linear position 1 mm 1 inch
Angular position 1 degree 1 degree
Linear velocity 1 mm/min 1 inch/min
Angular velocity 1 rpm 1 rpm
Linear acceleration 1 m/s
2
1 inch/s
2
Angular acceleration 1 rev./
s2
1 rev./s
2
Linear jerk 1 m/s
3
1 inch/s
3
Angular jerk 1 rev./s
3
1 rev./s
3
Time 1 s 1 s
Position controller servo gain 1/s 1/s
Rev. feedrate 1 mm/rev 1 inch/rev
Compensation value linear
position
1 mm 1 inch
Compensation value angular
position
1 degree 1 degree
The units listed below are used for storage. The control always uses these units internally
irrespective of the basic system selected.
Physical quantity: Internal unit:
Linear position 1 mm
Angular position 1 degree
Linear velocity 1 mm/s
Angular velocity 1 deg./s
Linear acceleration 1 mm/s
2
Angular acceleration 1 degree/s
2
Linear jerk 1 mm/s
3
Angular jerk 1 degree/s
3
Time 1 s
Position controller servo gain 1/s
Rev. feedrate 1 mm/degree
Compensation value linear position 1 mm
Compensation value angular position 1 degree
The user can define different input/output units for machine and setting data.
