2. OPERATION
Adjustment 4
Step
1
Set 0001 in parameter No. 8.
2
Set 0001 in parameter No. 9.
Switch servo on and perform operation several
3
times.
Make gain adjustment in either of the following
methods 1) and 2).
1) Set the machine's load inertia moment to
servo motor inertia moment in parameter No.
12. (When it is unclear, set an approximate
value.)

2) Switch servo on and perform operation
5
Set 0002 in parameter No. 8.
While confirming the operating status, adjust
the following parameters:
Parameter No. 13
Parameter No. 15
6
Parameter No. 14
Parameter No. 16
Parameter No. 17
Adjustment 5
Step
Adjust the gains of all axes in any of Adjustment
1
1 to 4 procedures. The gains of each axis are
adjusted.
Set 0001 or 0002 in parameter No. 8.
2
Set the following parameter of each axis to the
3
minimum value of all interpolation-controlled
axes: Parameter No. 13
Operation
Operation
Auto tuning is selected.
Response is set to low level.
Auto tuning is performed.
Check to see if vibration reduced.
Temporary adjustment
When this parameter value is set, the following
parameter values are set automatically. Each
value provides an ideal, hunting-less gain for
parameter No. 12 if machine resonance does not
occur.
Parameter No. 13
Parameter No. 14
Parameter No. 15
Parameter No. 16
Parameter No. 17
Auto tuning is performed.
Auto tuning is made invalid to enable manual
setting of parameters No. 13 to 17.
The optimum value is achieved just before
vibration begins to increase.
Increase the setting to reduce the settling time.
Note that overshoot is more liable to occur.
Increase the setting to improve servo response.
Note that vibration is more liable to occur.
Decrease the setting to keep the speed constant
to load disturbance and increase holding force
at a stop (servo rigidity). Note that overshoot
The gains of each axis are adjusted.
0001 "interpolation axis control": The values of
parameters No. 12 14 will change in
subsequent operation.
0002 "no": Auto tuning is made invalid to
enable manual setting of parameters No.
13 to 17.
The gains for operation of all axes are set to
the same value.
