Explanation
Torque limit function selection at instantaneous power
failure
(instantaneous power failure tough drive selection)
0: Disabled
1: Enabled
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. PX28
SEMI-F47 function - Instantaneous power failure
detection time].
To enable the torque limit function at instantaneous
power failure, select "Enabled (_ 1 _ _)" of "SEMI-F47
function selection" in [Pr. PX25].
This parameter setting is used with servo amplifier with
software version B0 or later.
