(2) Instantaneous power failure time of the control circuit power supply < [Pr. PF25 SEMI-F47 function -
Instantaneous power failure detection time]
Operation status differs depending on how bus voltage decrease.
(a) When the bus voltage decrease lower than 158 V DC within the instantaneous power failure time of
the control circuit power supply
[AL. 10 Undervoltage] occurs when the bus voltage decrease lower than 158 V DC regardless of the
enabled instantaneous power failure tough drive.
