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.
