F) Setting Of Acceleration/Deceleration Time And Acceleration/Deceleration Pattern; Setting The Acceleration And Deceleration Time - Mitsubishi Electric FR-F820-04750 Instruction Manual

Parameters
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 5-409, page 5-417).

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.
Select the increment

setting and the
setting range.
Set the acceleration/deceleration time for
JOG operation (from stop status to Pr. 20).
Refer to page 5-139
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 5-409, page 5-417.
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 time in a low-speed
range (less than 10% of the rated motor
frequency).
The acceleration time set in Pr. 7 is
applied. (While RT signal is ON, the second
function is enabled.)
Set the deceleration time in a low-speed
range (less than 10% of the rated motor
frequency).
The deceleration time set in Pr. 8 is
applied. (While RT signal is ON, the second
is enabled.)
