Description
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/deceleration time
when X9 signal is ON.
Third acceleration/deceleration is
disabled.
Set the deceleration time when X9 signal
is ON.
Acceleration time = deceleration time
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 or X9 signal is
ON, the second or third 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 or 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.
Output frequency > 10% of the rated motor frequency
Output frequency ≤ 10% of the rated motor frequency
