Command unit select function [G] [WG]

Speed command unit selection function [G] [WG]

This function is available on servo amplifiers with firmware version A5 or later.
This is a function to select setting units for speed data. Either r/min (mm/s) or command unit/s can be selected.
Setting unit
r/min, mm/s
Command unit/s
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].

Explanation
Use this when setting the speed data as servo motor speed (encoder unit).
Select r/min for rotary servo motors.
Select mm/s for linear servo motors.
Use this when setting the speed data in command units.
