Note 1: The power ride-through control time when WXE= depends on the setting of H, and the
deceleration time when WXE= depends on the setting of H.
Also, the deceleration time and the acceleration time when WXE= or depend on the setting of
H and that of H, 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 along with this parameter function.
Note 3: These functions do not operate at the time of torque control.
Note 4: Jog run function doesn't operate at synchronized acceleration/deceleration.
Note 5: Although the setting of H can be written when WXE is set to (non-stop control), it cannot be
written when WXE is set to (momentary power failure slowdown stop).
Note 6: For the parameter Hѽ 100% corresponds to 200V (200V class) or 400V (400V class).

#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.
