Acceleration/Deceleration - Mitsubishi Electric Melservo-Jet MR-JET-G Series User Manual

Acceleration/deceleration

Acceleration/deceleration is performed in accordance with the specified acceleration/deceleration [command unit/s
the acceleration/deceleration time constants, acceleration/deceleration can be performed independent of the rated speed of
the servo motor.
The control mode influences whether the acceleration/deceleration is set in the servo parameters, objects, or other settable
areas.
Setting example
To accelerate at 0.5 [s] from 0 [command unit/s] to 1500 [command unit/s], set 3000 [command unit/s
To decelerate at 2 [s] from 1500 [command unit/s] to 0 [command unit/s], set 750 [command unit/s

Precautions
• The parameter for setting the acceleration/deceleration 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. Refer to [Pr. PT01.1] for details. For the precautions for each acceleration/deceleration data,
refer to the setting parameters and objects.
Setting method
Select an acceleration/deceleration unit in [Pr. PT01.1 Speed/acceleration/deceleration unit selection].
