STOPPING OF DECELERATION AT POWER OFF
This is a function that decelerates and stops not to exceed over voltage level
(OV-LADSTOP : 052) after power turns off during running.
When selection of non-stop function at instanteneaous power failure is valid
(b050), if power stops during running and at voltage less than starting voltage
of non-stop function at instantaneous power of failure, at first the inverter
would decelerate at width of starting deceleration at non-stop instantaneous
power failure(b054) in width of frequency, and then it would decelerate at
non-stop deceleration time at instantaneous power failure(b153).
If it becomes over voltage due to genererating during deceleration (more than
non-stop OV-LADSTOP level at instantaneous power failure : b052), the condition would be in LAD stop until over voltage is released.

(Note 1) When non-stop OV-LADSTOP level at instantaneous power failure (b052) is less than starting voltage of
non-stop function at instantaneous power failure (b051), be sure to raise non-stop OV-LADSTOP level at
instantaneous power failure (b052) to starting voltage of non-stop function at instantaneous power failure
(b051) and to perform. (However, be sure not to change setteng range)
