Speed Command Unit Selection Function - Mitsubishi Electric MELSERVO-JET MR-JET User Manual

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.
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.
• Depending on the unit selected in [Pr. PT01.1], both the speed data and the unit of acceleration/deceleration data are
changed.
Setting method
Select the speed data setting unit in [Pr. PT01.1 Speed/acceleration/deceleration unit selection].

3.4 Command unit selection function
Explanation
Use this when setting the speed data as servo motor speed (encoder unit).
Use this when setting the speed data in command units.
[Pr. PT01.2 Unit for position data] can be used to change the command unit to "mm, inch, pulse" or "degree".
