(F) Setting of acceleration/deceleration time and
acceleration/deceleration pattern
Purpose
To set the motor acceleration/
deceleration time
To set the acceleration/
deceleration pattern suitable for
an application
To command smooth speed
transition with terminals
Starting frequency
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, or 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

Description
Set the frequency that is the basis of acceleration/deceleration time.
As acceleration/deceleration time, set the time required to change
the frequency from a stop status (0 Hz) to the frequency set in Pr.20
and vice versa.
Increment: 0.1 s
Select the increment for the acceleration/
deceleration time setting.
Increment: 0.01 s
Set the acceleration/deceleration time (time required to change the
frequency from a stop status (0 Hz) to the frequency set in Pr.20 and
vice versa) for JOG operation. (Refer to
Set the acceleration time for restart (from stop status to Pr.20).
Standard acceleration time (for example, Pr.7) is applied as the
acceleration time at restart. (Refer to
Set the motor acceleration time (time required to change the
frequency from a stop status (0 Hz) to the frequency set in Pr.20).
Set the motor deceleration time (time required to change the
frequency from the frequency set in Pr.20 to stop status (0 Hz)).
Set the acceleration/deceleration time used while the RT signal is
ON.
Set the deceleration time used while the RT signal is ON.
The acceleration time applies to the deceleration time.
Set the frequency where the acceleration/deceleration time switches
to the time set in Pr.44 and/or Pr.45.
Function disabled.
Set the acceleration time in a low-speed range (less than 1/10 of the
rated motor frequency).
The acceleration time set in Pr.7 is applied. (While the RT signal is
ON, the second function is enabled.)
