[Pr. PF25_SEMI-F47 function - Instantaneous power failure
detection time (Instantaneous power failure tough drive detection
time) (CVAT)]
Initial value
200 [ms]
Set the time until the occurrence of [AL. 010.1 Voltage drop in the control circuit power].
To comply with SEMI-F47 standard, it is not required to change the time from the initial value (200 ms).
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 turned off normally even if a value larger than 200 ms is set in this servo parameter.
This function is disabled when [Pr. PA20.2 SEMI-F47 function selection] is set to "0" (disabled).

[Pr. PF29_Function selection F-10 (*FOP10)]

Initial value
00000000h
[Pr. PF29.1_State selection with forced stop in progress]
Initial value
0h
Select the PDS state transition for when the forced stop is in progress.
Select whether to enable/disable use of the Quick stop function when the servo amplifier detects a forced stop signal off
during operation of the servo motor.
0: Operation enabled
1: Quick stop active
[Pr. PF31_Machine diagnosis function - Friction judgment speed
(FRIC)]
Initial value
0 [r/min], [mm/s]
Set the servo motor speed to divide the friction estimation area between low-speed and high-speed in the friction estimation
process of machine diagnosis.
When the maximum operation speed is under the rated speed, it is recommended to set half the value of the maximum
operation speed.
When "0" is set, the judgment speed is half of the rated speed.
The setting value will be clamped at the permissible maximum speed.
By setting [Pr. PF34.6 Friction estimate area judgment speed setting] to "1" (automatic setting), this servo parameter value will
be automatically calculated from the operation pattern during servo motor driving and overwrite the value.
