function
selection _ _ _ x Oscillation detection alarm selection
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.

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, set "Disabled (_ 0 _ _)" of "SEMI-F47 function selection"
in [Pr. PA20].
This parameter is not available with MR-J4-03A6 servo amplifiers.

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.
Setting "0" will set a value half of the rated speed.
When your operation pattern is under the rated speed, we recommend that you set a
half value of the maximum speed.
