6.12.2 Regenerative power ride-through control (Deceleration
stop)
: Regenerative power ride-through control (Deceleration stop)
Function
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.

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 .

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