Acceleration/deceleration 2

6.25.1 Setting acceleration/deceleration patterns and switching
acceleration/deceleration patterns 1 and 2
 : Acceleration time 2
 : Deceleration time 2
 : Acceleration/deceleration 1 pattern
 : Acceleration/deceleration 2 pattern
 : Panel acceleration/deceleration selection
 : Acceleration/deceleration switching frequency
• Function
Four acceleration times and two deceleration times can be specified individually. The selection/switching
mode can be selected from the following 3 options:
1) Selection by means of parameters
2) Switching by means of frequencies
3) Switching by means of terminals

Note: The minimum setting of acceleration and deceleration times have been set respectively at 0.1 sec. by default,
but they can be changed within a range of 0.01 sec. (setting range:0.01~600.0 sec.) by changing the setting of
the parameter  (default setting).
⇒ For details, refer to Section 5.20.

Acceleration/deceleration time 1 is initially set as the default. Acceleration/deceleration time 2 can be selected by
changing the setting of the .
