2. OPERATION
Adjustment 2
Step
Set 0101 in parameter No. 2.
1
Set the machine's load inertia moment to servo
motor inertia moment in parameter No. 34.
(When it is unclear, set an approximate value.)
2
Set
2
in parameter No. 2.
3
In parameter No. 37, set a value about 100
4
smaller than the value set automatically in step 3.
5
Execute steps 2 to 4 of Adjustment 1.
When machine response does not occur any
more, confirm the operating status, and at the
6
same time, gradually increase the setting of
parameter No. 37 reduced in step 4.
To reduce the settling time, increase the
response level of parameter No. 2 sequentially
7
and execute steps 1 to 6.
Adjustment 3
Step
Set 0101 in parameter No. 2.
1
Set the machine's load inertia moment to servo
motor inertia moment in parameter No. 34.
(When it is unclear, set an approximate value.)
2
Switch servo on and perform operation several
3
If vibration still persists, execute steps 2 and 3.
4
If vibration occurs due to machine resonance,
make adjustment in the
5
procedure of Adjustment 1 or 2.

Description
Auto tuning is selected.
Response is set to low level.
When this parameter value is set, the following
parameter values are set automatically. Each value
provides an ideal, hunting-less gain for parameter
No. 34 if machine resonance does not occur.
• Parameter No. 6
• Parameter No. 35
• Parameter No. 36
• Parameter No. 37
• Parameter No. 38
Auto tuning is made invalid to enable manual
setting of parameters No. 6 • 35 to 38.
The optimum value is achieved just before
vibration begins to increase.
Set a value which is about 50 to 100 smaller than
the set value at which gear noise and/or vibration
begins to be generated by machine resonance.
