6.19.2 Regenerative power ride-through control/Deceleration stop
during power failure/Synchronized acceleration/deceleration
f302 : Regenerative power ride-through control (Deceleration stop)
f317 : Synchronized deceleration time
f318 : Synchronized acceleration time
• 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 the load.
 When the function of the deceleration stop during power failure operates,
the message “” is displayed on the operation panel.
 After the forced stop, the inverter remains static until you put off the operation command
momentarily.
3) Synchronized acceleration/deceleration:
When the inverter is used with textile machines, this function decelerate the motors synchronously to
stop in the event of a momentary power failure and accelerate them to reach the targeted frequency
commands synchronously at the recovery from the power failure in order to prevent thread breakage.
