f302
Regenerative power ride-through
control (Deceleration stop)
0: Disabled
1: Regenerative power ride-through control
2: Deceleration stop during power failure
3: Synchronized acceleration / deceleration

f317
Synchronized deceleration time
(time elapsed between start of
deceleration to stop)
0.0-3600 (360.0) (s) 2.0
f318
Synchronized acceleration time
(time elapsed between start of
acceleration to achievement of
specified speed)
0.0-3600 (360.0) (s) 2.0
Note 1: The deceleration time and the acceleration time when f302=3 or 4 depend on the setting of f317
and that of f318, respectively.
Note 2: Even if these functions are used, a motor may coast according to load conditions.
In this case, use the auto-restart function (f301) for the smooth restart after power supply is restored .
Note 3: Jog run function doesn't operate at synchronized acceleration/deceleration.
An example of setting when f302=1
[When power is interrupted]
●The time for which the operation of the motor
can be continued depends on the machine
inertia and load conditions. Before using this
function, therefore, perform verification tests.
●Use with the retry function allows the motor to
be restarted automatically without being
brought to an abnormal stop.

About 100ms~10s

Note 4: If power is interrupted during deceleration stop, power ride-through control will not be performed.
