[Pr. PF21_Drive recorder switching time setting (DRT)]
Set the drive recorder switching time.
When communication is shut off during the use of a graph function, the function will be switched to the drive recorder function
after the time set in this servo parameter has passed.
When any value of "1" to "32767" is set, the drive recorder function will be switched after the time set in this servo parameter
has passed.
When any value of "0" to "9" is set, the drive recorder function will be switched after 10 s.
When "-1" is set, the drive recorder function is disabled.
[Pr. PF23_Vibration tough drive - Oscillation detection level
(OSCL1)]
Set the oscillation detection level for readjusting the machine resonance suppression filter while the vibration tough drive is
enabled.
When the oscillation level is higher than the setting value of this servo parameter, reset [Pr. PB13 Machine resonance
suppression filter 1] or [Pr. PB15 Machine resonance suppression filter 2].
When "0" is set, the oscillation detection level is 20 %.
[Pr. PF24_Function selection F-9 (*FOP9)]
[Pr. PF24.0_Oscillation detection alarm selection]
Select the alarm output at oscillation detection.
Select whether to generate an alarm or a warning when an oscillation continues at a level set in [Pr. PF23 Vibration tough
drive - Oscillation detection level].
This function is enabled regardless of the setting of [Pr. PA20.1 Vibration tough drive selection].
0: Alarm ([AL. 054 Oscillation detection])
1: Warning ([AL. 0F3.1 Oscillation detection warning])
2: Oscillation detection function disabled (oscillation detection not processed)
[Pr. PF25_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].
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 Instantaneous power failure tough drive selection] is set to "0" (disabled).
