stop
H
: Regenerative power ride-through control/Deceleration stop
•
Function
1) Regenerative power ride-through control 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 dur-
ing operation, the inverter stops forcibly. (Deceleration time varies with control.) When operation is
stopped, the message “
UVQR
” is displayed (alternately) on the operation panel.
After the forced stop, the inverter remains static until you put off the operation command momen-
tarily.

Note: Even when this parameter is set, the particular load conditions may cause the motor to coast. In this
case, use the auto-restart function

along with this parameter function.

Input voltage
* 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.
