Command unit selection function
Speed command unit selection function
This is a function to select setting units for speed data. Either r/min (mm/s) or command unit/s can be selected.
Precautions
• The servo parameter for setting the speed data varies depending on the unit selected in [Pr. PT01.1 Speed/acceleration/
deceleration unit selection]. However, the same object is used for setting the acceleration/deceleration data regardless of
the unit selected.
• Not only the unit of speed data but also that of acceleration/deceleration data changes depending on the unit selected in
[Pr. PT01.1].
Setting method
Select the speed data setting unit in [Pr. PT01.1 Speed/acceleration/deceleration unit selection].
Relevant speed data and acceleration/deceleration data
Setting unit
Explanation
r/min, mm/s
Use this when setting the speed data as servo motor speed (encoder unit).
Command unit/s
Use this when setting the speed data in command units.
