Acceleration/Deceleration Waveform Adjustment When Specifying Jerk - Mitsubishi Electric MELSEC iQ-R Series User Manual

Acceleration/deceleration waveform adjustment when specifying
jerk
When the jerk acceleration/deceleration (J  0.0) is specified, the acceleration waveform and the deceleration waveform are
adjusted whether the values of the target velocity (V), the target acceleration (A), the target deceleration (Dec), and the jerk
(J) satisfy the following condition or not.
A 2
≥
For acceleration : V
J
When the condition is satisfied
The target acceleration (deceleration) can be reached.
The maximum acceleration section time and the maximum deceleration section time are adjusted by the speed, the
acceleration, the deceleration, and the jerk, and the waveform changes to reach the target velocity at the end of acceleration.
For the acceleration time and the deceleration time, refer to the following.
