Pn59
Setting range
• Use these parameters to set acceleration and deceleration times for the speed command inside
the Servo Drive.
• A soft start can be set when inputting speed commands of stepping movement or when using
internally set speed.
• Do not set acceleration and deceleration times when using the Servo Drive in combination with an
external position loop. (Set both Pn58 and Pn59 to 0.)
• Refer to 5-13 Soft Start on page 5-28 for more information on the soft start function.

Pn5A
Setting range
• Use this parameter to set the pseudo-S-curve acceleration/deceleration value to add to the speed
command to enable smooth operation. This parameter is useful for applications where impact may
occur due to a large change in acceleration or deceleration when starting or stopping with linear
acceleration or deceleration.
