[Pr. PF20_Friction failure prediction - Compensation coefficient 2
(TIC)]
Initial value
0 [0.1 %]
Set compensation coefficient 2 to compensate the dynamic friction being used for the friction failure prediction.
When the friction failure prediction warning selection is set to the automatic threshold setting, the value will be calculated
automatically from the estimated dynamic friction.
When performing threshold manual setting on an equipment for which the threshold setting has been made once, set the
value that has been calculated by the threshold automatic setting.
Setting this servo parameter decreases the possibility of erroneous detection of friction failure prediction, even with the
manual threshold setting.

[Pr. PF21_Drive recorder switching time setting (DRT)]

Initial value
0 [s]
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)]
Initial value
20 [%]
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)]

Initial value
00000000h
[Pr. PF24.0_Oscillation detection alarm selection]
Initial value
0h
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)
