Excuse me, how can I adjust the axis acceleration?

Thank you.

in your INI file [AXIS_n]-section you can define MAX_ACCELERATION

I may not know much about this, but isn't this the way to adjust the maximum acceleration? If this is adjusted, how should the maximum limit acceleration be set?
Thank you for your reply!

I may not be very good at using this forum. I don't know if you can receive my reply?

I think I don't understand what you are trying to do. What would be the difference between 'maximum acceleration' and 'maximum limit acceleration'?

Thank you very much for your reply. I want to set an acceleration and the maximum acceleration. I don't know how to modify these two data. What your said should be acceleration. I don't know if I have expressed my meaning clearly. My English is not very good.
Thank you again for your reply

It is equivalent to setting an acceleration and a maximum limit acceleration. The acceleration I set cannot exceed this maximum limit acceleration

The idea is that the user sets only the acceleration limits his machine setup can handle.
You can set limit accelerations for the machine as whole, for a joint (used for movements in joint mode) and for an axis (used after homing).
The actual acceleration is then determined by the motion planner that tries to maintain constant velocity and one of it's tasks is to make sure acceleration does not exeed any limits set by the user.

Yes, it is necessary to add limited acceleration. How can I set it
Thank you very much

in your INI file

[TRAJ]-section you can define MAX_LINEAR_ACCELERATION
[JOINT_n]-section you can define MAX_ACCELERATION
[AXIS_n]-section you can define MAX_ACCELERATION
