3. Operating Procedures
(1) Overall setup
Read the following instructions and check if your machine is in safe condition. If there
is no problem, use the default settings for making measurements.
(A) Frequency range
Set the machine resonance frequency measurement range as directed below.
• If the approximate resonance frequency is already known:
Set a frequency range that covers about 5 times the approximate resonance
frequency.
• If an approximate resonance frequency is not known:
Select a range of up to 900 Hz.
After measuring the resonance frequency, set a frequency range that covers
about 5 times the measured resonance frequency, and then measure the
resonance frequency again to obtain a more accurate result.
(B) Torque
Set the diagnostic signal amplitude during mechanical system diagnostic
measurements.
Setting a higher amplitude (100% or less) ensures more accurate measurements.
However, the higher the amplitude, the greater the torque applied to the machine,
so use caution.
(C) Speed
Operation proceeds at a constant speed during mechanical system diagnosis. Set a
speed command to specify the constant speed.
Enter a sufficiently high speed in a range from 100 min
-1
on up to the rated speed.
This speed must remain constant and must cause no machine damage.
Note 1: When "Linear Motor" is selected, the units are "mm/s".
(D) Allowable (allowable operation range)
Displays the allowable distance (amount of rotation) the machine can move during
mechanical system diagnosis. The machine immediately stops after mechanical
system diagnosis ends, but moves slightly more than the displayed value due to the
inertia of the machine. Set a longer distance to allow the machine to move slightly
more than the displayed distance (amount of rotation). To do this, decrease the
speed command value or reduce the operation adjustment range (see (G) in the
detailed setting dialog box).
Note 2: When "Linear Motor" is selected, the units are "mm".
