If auto gain adjustment is valid, the parameters listed above can’t be manually modified.
Only when Pr0.02 = 0x00 or 0x10, can the gain related parameters be modified manually.
Gain related parameters that don’t change with the real time gain adjustment
No.

mode
Used to set motion setting mode, which can be selected according to the
motion characteristics or setting requirements. Generally, it is
recommended to select mode 1 with good generality when there is no
special requirement, mode 2 when rapid positioning is needed If mode 1
and mode 2 cannot meet the requirements, please choose mode 0.
0:Manual
Pr0.03 invalid. Gain value must be adjusted manually
and accordingly.
1:Standard
Pr0.03 valid. Quick gain adjusting can be achieved by
changing Pr0.03 stiffness value. Gain switching is not
used in this mode, suitable for applications with
requirements for stability.
2:Positioning
Pr0.03 valid. Quick gain adjusting can be achieved by
changing Pr0.03 stiffness value. This mode is suitable
for applications requiring quick positioning. Not
recommended for load mounted vertical to ground, or
please compensate for the load using Pr6.07
0x0_0 Load type
setting
Used to select the load type, choose according to load-inertia ratio and
mechanical structure.
0: Rigid
structure
This mode prioritizes system responsiveness. Use this
mode when there is a relatively rigid structure with low
load inertia. Typical application including directly
connected high-precision gearbox, lead screw, gears,
etc.
1:High inertia
For applications with higher load inertia (10 times or
above), gain settings take into account both machine
stability and responsiveness. Not recommended to set
stiffness above 15 for high load inertia.
