When an instantaneous power failure occurs during operation, you can save electric
energy charged in the capacitor in the servo amplifier by limiting torque at
acceleration. You can also delay the time until [AL. 10.2 Voltage drop in the main
circuit power] occurs with instantaneous power failure tough drive function. Doing
this will enable you to set a longer time in [Pr. PF25 SEMI-F47 function -
Instantaneous power failure detection time].
The torque limit function at instantaneous power failure is enabled when "SEMI-F47
function selection" in [Pr. PA20] is "Enabled (_ 1 _ _)".
