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
.
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: 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 4: For the parameter
H
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.
