(F) Setting of acceleration/deceleration time and acceleration/deceleration pattern Parameters
5 - 102
5.5.1 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 5-415, page 5-423).
Initial value for the FR-F820-00340(7.5K) or lower and FR-F840-00170(7.5K) or lower.
Initial value for the FR-F820-00490(11K) or higher and FR-F840-00250(11K) and higher.

Acceleration/deceleration
reference frequency
60 Hz 50 Hz 1 to 590 Hz
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.

F002
Jog acceleration/
deceleration time
0.5 s 0 to 3600 s
Set the acceleration/deceleration time for
JOG operation (from stop status to Pr. 20).
Refer to page 5-144
611
F003
Acceleration time at a
restart
9999 0 to 3600 s, 9999
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 5-415, page 5-423.

Set the motor acceleration time (from
stop status to Pr. 20).

0 to 3600 s
Set the motor deceleration time (from
Pr. 20 to stop status).

F020
Second acceleration/
deceleration time
5 s 0 to 3600 s
Set the acceleration/deceleration time
when the RT signal is ON.
45
F021
Second deceleration time 9999
0 to 3600 s
Set the deceleration time when the RT
signal is ON.
9999 Acceleration time = deceleration time
147
F022
Acceleration/deceleration
time switching frequency
9999
0 to 590 Hz
Set the frequency where the acceleration/
deceleration time switches to the time set
in Pr. 44 and Pr. 45.
9999 No function
791
F070
Acceleration time in low-
speed range
9999
0 to 3600 s
Set the acceleration time in a low-speed
range (less than 10% of the rated motor
frequency).
9999
The acceleration time set in Pr. 7 is
applied. (While RT signal is ON, the second
function is enabled.)
792
F071
Deceleration time in low-
speed range
9999
0 to 3600 s
Set the deceleration time in a low-speed
range (less than 10% of the rated motor
frequency).
9999
The deceleration time set in Pr. 8 is
applied. (While RT signal is ON, the second
is enabled.)
