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 decreases.
■
When the bus voltage decreases to the undervoltage level or lower within instantaneous
power failure time of control circuit power supply
[AL. 10 Undervoltage] occurs when the bus voltage decreases to the undervoltage level or lower regardless of the enabled
instantaneous power failure tough drive.
*1 For the undervoltage level, refer to "[AL. 10.2 Voltage drop in the main circuit power] will occur when bus voltage is as follows." in
"Parameter setting" below.
