6.19 Trip-less intensification

6.19.1 Auto-restart (Restart of coasting motor)
f301 : Auto-restart control selection
Refer to section 5.9 for details.
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
2) Deceleration stop during power failure:

function makes operation continue using the regeneration
energy from a motor.
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 control.) When operation
is stopped, the message "" blinks on the operation panel.
After the forced stop, the inverter remains static until you put off
the operation command momentarily.
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.
