Common
PF21 DRT Drive recorder switching time setting
Set a drive recorder switching time.
When a USB communication is cut during using a graph function, the function will be
changed to the drive recorder function after the setting time of this parameter.
When a value from "1" to "32767" is set, it will switch after the setting value.
However, when "0" is set, it will switch after 600 seconds.
When "-1" is set, the drive recorder function is disabled. 0

Common
PF23 OSCL1 Vibration tough drive - Oscillation 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.

_ _ _ x Oscillation detection alarm selection
0: [AL. 54 Oscillation detection] will occur at oscillation
detection.
1: [AL. F3.1 Oscillation detection warning] will occur at
oscillation detection.
2: Oscillation detection function disabled
Select alarm or warning when a 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].

PF25 CVAT SEMI-F47 function - Instantaneous power failure detection time
Set the time of the [AL. 10.1 Voltage drop in the control circuit power] occurrence.
To disable the parameter, select "Disabled (_ 0 _ _)" of "SEMI-F47 function selection"
in [Pr. PA20].
This parameter is not available with MR-J4W2-0303B6 servo amplifiers. 200

Common
PF31 FRIC Machine diagnosis function - Friction judgement speed
Set a (linear) servo motor speed that divides a friction estimation area into high and
low during the friction estimation process of the machine diagnosis.
However, setting "0" will be the value half of the rated speed.
When your operation pattern is under rated speed, we recommend that you set half
value to the maximum speed with this.
