It is a very bad example, with a very old VFD.
No, just HAL and a PID. This subject has been covered many times before. You should be able to find sample HAL files if you search the forum.

Nice hear it, send me the youtube link i want watch it.

The gear in my machine is practically 1x1. Did you use ladder logic to control it?

I stress that a more modern VFD will work better:

I found some subjects about spindle orient but any similar mine.
Asynchronous spindle motor.

Works fine for me.

What a kind of encoder did you use?

At that point it was a home-made 50-slot wheel.
It will generally work better with a higher-count encoder.

I found this. What you think?

That Wiki page describes spindle speed control, not position control.
Try reading this thread: linuxcnc.org/hardy/dapper/index.php/engl...-211?start=250#51172
Unfortunately it took a lot of iterations to get to a working setup.

I think using closed loop is too complex for me. I don't know hal config well. I set my machine using pncconf. I'm thinking to do something more simple. Use fixed frequency and brake cc in the inverter.
I'm thinking something like that, tell me what you think.
Set some pon from M19 linked with classic ladder. Maybe that motion.spindle-orient or another.
When M19 is called that pin come true in classic ladder, then i will set an classic ladder output to set a fixed frequency on the inverter throught an digital input. I will use a inductive sensor with a dog to define the right position stop. I will link that sensor to a classic ladder input, and then set another classic ladder out to set a inverter brake CC, ready the spindle is stoped.
In theory it works, what you think? If you think it works, could you please help me?
