7. SPECIAL ADJUSTMENT FUNCTIONS
7 - 28
(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 undervoltage level within the instantaneous power failure
time of the control circuit power supply
[AL. 10 Undervoltage] occurs when the bus voltage decrease lower than undervoltage level
regardless of the enabled instantaneous power failure tough drive.
