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

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

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

Friction
judgement
speed
Set a 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.
