automatically
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 Acceleration time at a
restart (page 515).

Description
Set the frequency that will be the basis of
acceleration/deceleration time. As acceleration/
deceleration time, set the frequency change time from
a stop status to Pr.20.
Increment: 0.1 s
Increment: 0.01 s
Set the acceleration/deceleration time for JOG
operation (from stop status to Pr.20).
Refer to page 312.
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.
Refer to page 515.
Set the motor acceleration time (from stop status to
Pr.20).
Set the motor deceleration time (from Pr.20 to stop
status).
Set the acceleration/deceleration time when the RT
signal is ON.
Set the deceleration time when the RT signal is ON.
Acceleration time = deceleration time
Set the frequency where the acceleration/deceleration
time switches to the time set in Pr.44 and Pr.45.
No function
Set the acceleration/deceleration time when X9 signal
is ON.
Third acceleration/deceleration is disabled.
