PF23 OSCL1 Vibration tough drive - Oscillation detection level
This is used to set a filter readjustment sensitivity of [Pr. PB13 Machine resonance
suppression filter 1] and [Pr. PB15 Machine resonance suppression filter 2] while the vibration
tough drive is enabled.
However, setting "0" will be 50%.
Example: When you set "50" to the parameter, the filter will be readjusted at the time of 50%
or more oscillation level.

Select alarm or warning when a oscillation continues at a filter
readjustment sensitivity level of [Pr. PF23].
The digit is continuously enabled regardless of the vibration tough
drive in [Pr. PA20].

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].

PF31 FRIC Machine diagnosis function - Friction judgment speed
Set a (linear) servo motor speed to divide a friction estimation area into high and low for 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.
