1 SERVO PARAMETER DETAILS
1.7 Extension setting 3 servo parameters group ([Pr. PF_ _ ])
[Pr. PF25_SEMI-F47 function - Instantaneous power failure
detection time (Instantaneous power failure tough drive detection
time) (CVAT)]
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)]
[Pr. PF29.1_State selection with forced stop in progress]
Select the PDS state transition for when the forced stop is in progress.
When the servo amplifier detects the forced stop signal off during servo motor rotation, the PDS state transition destination
can be selected.
