Drive
recorder
switching
time setting This is used to 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
setting 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.
Setting range: -1 to 32767 0

Vibration
tough drive -
Oscillation
detection
level This is used to 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.
Example: When you set "50" to the parameter, the filter will be readjusted at the
time of 50% or more oscillation level.
Setting range: 0 to 100 50

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.
2: Oscillation detection function disabled

detection time) Set the time of the [AL. 10.1 Voltage drop in the power] occurrence.
To disable the parameter, select "Disabled (_ 0 _ _)" of "SEMI-F47 function selection
(instantaneous power failure tough drive selection)" in [Pr. PA20].
When "Enabled (_ 1 _ _)" is selected of "SEMI-F47 function selection (instantaneous
power failure tough drive selection)" in [Pr. PA20], the power should be off for the
setting value of this par 1.5 s or more before cycling the power to enable a
parameter whose symbol is preceded by "*".

FRIC
Machine
diagnosis
function -
Friction
judgement
speed Set a servo motor speed to divide a friction estimation area into high and low for 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.
