PF25 CVAT SEMI-F47 function - Instantaneous power failure detection time
Set the time of the [AL. 10.1 Voltage drop in the control circuit power] occurrence.
This parameter setting range differs depending on the software version of the servo
amplifier as follows.
Software version C0 or later: Setting range 30 ms to 200 ms
Software version C1 or earlier: Setting range 30 ms to 500 ms
To comply with SEMI-F47 standard, it is unnecessary to change the initial value (200
ms).
However, when the instantaneous power failure time exceeds 200 ms, and the
instantaneous power failure voltage is less than 70% of the rated input voltage, the
power may be normally turned off even if a value larger than 200 ms is set in the
parameter.
To disable the parameter, select "Disabled (_ 0 _ _)" of "SEMI-F47 function selection"
in [Pr. PA20].
This parameter is not available with MR-J4W2-0303B6 servo amplifiers.

PF31 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.
However, setting "0" will be the value half of the rated speed.
When your operation pattern is under rated speed, we recommend that you set half
value to the maximum speed with this.
