6.13.2 Regenerative power ride-through control (Deceleration
stop)
 : Regenerative power ride-through control (Deceleration stop)
 Function
1) Regenerative power ride-through control:
This function continues the operation of the motor by utilizing motor regenerative energy in the
event of momentary power failure.
2) Slowdown stop in the event of momentary power failure:
If a momentary power failure occurs during operation, the inverter stops forcibly. (Deceleration time
varies with control.) When operation is stopped, the message "" is displayed (alternately)
on the operation panel.
After the forced stop, the inverter remains static until you put off the operation command
momentarily.

Note 1: Even when this parameter is set, the particular load conditions may cause the motor to coast. In this
case, combine  (auto-restart function) to restart quickly after recovery.
