Note 1: 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 .

stop)

1) Regenerative power ride-through control:

When momentary power failure occurs during operation, this function makes operation continue
using the regeneration energy from a motor.
2) Deceleration stop during power failure:
When momentary power failure occurs during operation, this function stops the motor quickly and
compulsorily using the regeneration energy from the motor.
 Deceleration time varies according to load.
 When deceleration stop during power failure is operated, the message "" displays on the
operation panel.
 After the forced stop, the inverter remains static until you put off the operation command
momentarily.

●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.
