Parameters (F) Setting of acceleration/deceleration time and acceleration/deceleration pattern
FR-A800 5 - 241
5.8 (F) Setting of acceleration/deceleration time and
acceleration/deceleration pattern
5.8.1 Setting the acceleration and deceleration time
The following parameters are used to set motor acceleration/deceleration time.
Set a larger value for a slower acceleration/deceleration, and a smaller value for a faster acceleration/
deceleration.
For the acceleration time at automatic restart after instantaneous power failure, refer to Pr. 611 "Ac-
celeration time at a restart" (page 5-581, page 5-590).

Set the acceleration time for restart (from
stop status to Pr. 20).
When "9999" is set, standard acceleration
time (like Pr. 7) is applied as the
acceleration time at restart.
