time setting Set a drive recorder switching time.
When a USB communication is cut during using a graph function or a graph function
is terminated, the function will be changed to the drive recorder function after the
settling time of this parameter.
When a value from "1" to "32767" is set, it will switch after the setting value.
When "0" is set, it will switch after 600 s.
When "-1" is set, the drive recorder function is disabled.

detection
level 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 an 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].
0: [AL. 54 Oscillation detection] will occur at oscillation detection.
1: [AL. F3.1 Oscillation detection warning] will occur at oscillation detection.

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 earlier: Setting range 30 ms to 200 ms
Software version C1 or later: 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, set "Disabled (_ 0 _ _)" of "SEMI-F47 function selection"
in [Pr. PA20].
This parameter is not available with MR-J4-03A6(-RJ) servo amplifiers.
Setting range: 30 to 500
