Parameters Controlling Operation of Real-time Auto Tuning
●
Configure the real-time auto tuning operation by setting the following parameters.
Class No.

0
02
Real-time auto-gain
tuning setup
Specifies the operation mode of real-time auto tuning.

Description
0
Invalid
The real-time auto tuning
function is disabled.
1
Synchronization
Mode for synchronization
control.Offset load compensation
and friction compensation are not
performed. The command filter
will be maintained. Use this
mode first. If there is any
problem, use the other mode.
2
Synchronous
friction
compensation
In addition to the synchronization
mode, dynamic friction/viscous
friction compensation is applied.
Use this mode for a load with
large friction.
3
Stiffness setup
Inertia ratio estimation, offset
load compensation, and friction
compensation are not performed,
and only the gain filter setup
corresponding to the stiffness
table is updated.
For a load with large inertia
variations, estimate the inertia in
the synchronization mode, etc.,
and then use this mode.
4
Load
characteristic
update
In the gain filter setup, only the
inertia ratio and dynamic
friction/viscous friction
compensation are applied among
load characteristics.
5
Load
characteristic
measurement
Basic gain settings and friction
compensation settings are not
changed and load characteristic
estimation only is made. This is
used in combination with set-up
support software (PANATERM).
6
Load change
support mode
Use this mode to make robust
adjustments in load change.
0
03
Selection of machine
stiffness at real-time
auto-gain tuning
Specifies the response for enabled real-time auto tuning.
A larger setting increases the speed response and servo
stiffness but invites more vibration.
Gradually increase the setting while monitoring the
operation.

setup
The automatic adjustment of load change inhibit function is
enabled with bit14=1.
