Operation DescriptionStep
Set 0101 in parameter No. 2.
Switch servo on and perform operation several
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.
34. (When it is unclear, set an approximate
value.)
2) Switch servo on and perform operation
Set 2 in parameter No. 2.
While confirming the operating status, adjust
the following parameters:
• Parameter No. 36
• Parameter No. 37
• Parameter No. 38
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. 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 performed.
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.
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
• Parameter No. 6
• Parameter No. 35
Increase the setting to reduce the settling time.
Note that overshoot is more liable to occur.

Set the following parameter of each axis to the
minimum value of all interpolation-controlled
axes: • Parameter No. 6
Step Operation Description
Adjust the gains of all axes in any of
Adjustment 1 to 4 procedures.The gains of each
axis are adjusted.
Set 0 or 2 in parameter No. 2.
The gains of each axis are adjusted.
The gains for operation of all axes are set to
the same value.

"no": Auto tuning is made invalid to
enable manual setting of parameters
No. 6 • 35 to 38.
"interpolation axis control": The values
of parameters No. 34 • 35 • 37 • 38
will change in subsequent operation.
