• 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 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.
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
