stop
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.

* The time for which the operation of the motor can be
continued depends on the machine inertia and load
conditions. Before using this function, therefore,
perform verification tests.
