Description
Set the frequency that is 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
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 (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.
Without the function
Set the acceleration/deceleration time when the X9 signal is ON.
Third acceleration/deceleration is disabled.
Set the deceleration time when the X9 signal is ON.
Acceleration time = deceleration time
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 or
the X9 signal is ON, the second or third function is enabled.)
Set the deceleration time in a low-speed range (less than 1/10 of the
rated motor frequency).
The deceleration time set in Pr.8 is applied. (While the RT signal or
the X9 signal is ON, the second or third function is enabled.)
Set the motor deceleration time at a deceleration by turning ON the
X92 signal.
