PF25 Set the time of the [AL. 10.1 Voltage drop in the power] occurrence.
CVAT To disable the parameter, select "Disabled (_ 0 _ _)" of "Instantaneous power failure
tough drive selection" in [Pr. PA20].
instantaneous
power failure When "Enabled (_ 1 _ _)" is selected of "Instantaneous power failure tough drive
tough drive - selection" in [Pr. PA20], the power should be off for the setting value of this
detection time parameter + 1.5 s or more before cycling the power to enable a parameter whose
symbol is preceded by "*".
Setting range: 30 to 2000
PF31 Set a servo motor speed to divide a friction estimation area into high and low for the
friction estimation process of the machine diagnosis.
FRIC
However, setting "0" will be the value half of the rated speed.
