Command unit selection function

Speed command unit selection function

This is a function to select setting units for speed data. Either r/min or command unit/s can be selected.
Setting unit
r/min
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 object is the same regardless of the unit selected.
• Depending on the unit selected in [Pr. PT01.1], not only the speed data but also the unit of acceleration/deceleration data is
changed.
Setting method
Select the speed data setting unit in [Pr. PT01.1 Speed/acceleration/deceleration unit selection].
Servo parameter Symbol
PT01.1 **CTY
Relevant speed data and acceleration/deceleration data
[Pr. PT01.1 Speed/acceleration/deceleration unit selection]
0
[Pr. PC24 Forced stop deceleration time constant]
[Pr. PT05 Homing speed]
[Pr. PT06 Creep speed]
[Pr. PT56 Homing acceleration time constant]
[Pr. PT57 Homing deceleration time constant]
[Pr. PT67 Speed limit]
Explanation
Use this when setting the speed data as servo motor speed (encoder unit).
Use this when setting the speed data in command units.
