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.

PX24 FRIC Machine diagnosis function - Friction judgment speed
Set a (linear) servo motor speed that divides a friction estimation area into high and low during
the friction estimation process of the machine diagnosis.
Setting "0" will set a value half of the rated speed.
When your operation pattern is under the rated speed, we recommend that you set a half
value of the maximum speed.

Selecting "1" enables to suppress vibrations by automatically
changing setting values of [Pr. PB13 Machine resonance

filter 2] in case that the vibration exceeds the value of the oscillation
level set in [Pr. PX26].
