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
110
F030
Third acceleration/
deceleration time
9999
0 to 3600 s
Set the acceleration/deceleration time
when X9 signal is ON.
9999
Third acceleration/deceleration is
disabled.
111
F031
Third deceleration time 9999
0 to 3600 s
Set the deceleration time when X9 signal
is ON.
9999 Acceleration time = deceleration time
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 or X9 signal is
ON, the second or third 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 or X9 signal is
ON, the second or third function is
enabled.)
1103
F040 Deceleration time at
emergency stop
5 s 0 to 3600 s
Set the motor deceleration time at a
deceleration by turning ON the X92 signal.
