5. PARAMETERS
No. Symbol
PF25 CVAT Instantaneous power failure tough drive - Detection time
Set the time until the occurrence of [AL. 10.1 Voltage drop in the power].
To disable the parameter, select "Disabled (_ 0 _ _)" of "instantaneous power failure tough
drive selection" in [Pr. PA20].
When "Enabled (_ 1 _ _)" of "instantaneous power failure tough drive selection" is selected in
[Pr. PA20], the power should be off for the setting value of this parameter +1 s or longer
before the power is cycled to enable a parameter whose symbol is preceded by "*" or "**".
PF31 FRIC Machine diagnosis function - Friction judgment speed
Set a servo motor speed to divide a friction estimation area into high and low for the friction
estimation process of the machine diagnosis.
However, when "0" is set, the value will be half of the rated speed.
When your operation pattern is under the rated speed, we recommend that you set half value
of the maximum speed with this.
