• Settings of acceleration/deceleration time for line speed command are used in the command for accelerating/decelerating
the line speed.
• Use Pr.393 Line speed command acceleration/deceleration reference for setting time in each parameter.
• Use Pr.21 Acceleration/deceleration time increments to set the minimum increment of the acceleration/deceleration
time.
