I've seen various threads on calculation of speed of motors, but I still have some doubts.

Here is an example below:
PPS = 2000
PPR = 200 * 2 "half step"
RPM: 2000 * 60/400 = 300

We got to the 300rpm value.

From what I saw in other topics the calculation to find the rmp is this, correct me if I'm wrong.

But I have some questions regarding the pps:
The pps is the kernel speed?
If the kernel speed on some topics the staff uses value in pps as 2000.4000 and other values but in the mach3 has only the options 25000Hz, 35000Hz, 45000Hz.
The configuration Step Pulse and Pulse Dir in engine tuning has something to do?

There are a couple of useful stepper motor calculations, including speed, here.

The Mach3 kernel speed is the maximum pps it can send. If you only need 2000, then just set it at 25Khz.
Your stepper drive will have minimum pulse width requirements. You can usually just set them to between 2 and 5 and it should work fine.

OK,
Can I have me confused with some other settings, but where do I change the pps for 2000 or 4000 or other value, or the value of pps is generated automatically?
Thanks for the reply!

You specify the number of steps per unit of distance, and the feedrate, and the pulses per second (pps) are automatically determined. It's not a constant number, as the rate of the pulses changes when accelerating and decelerating, and with changes in feedrate.

Yes,
But let's say that I need a size stepper motor how do I know if the pps will be in 1000, 2000, ..., 6000 as in image table in annex.
To scale need to know because as varies the pps also vary the speed and torque.
Thank you!!!

Pps=pulses per second.

The church shows a stepper motors target as rpms increase the higher the RPMs the list torque the motor will have

Let's see the following I need a 10kgf stepper motor for my design machine specifications the image attached.
As an example we get the following information:
Steps per: 63.68
Velocity in mm's per min: 10002
Acceleration: 300
Step Pulse = 17
Dir Pulse = 13
Drive mode = 1/10

From this information what is the pps output?
The image of the engine that is in annex meets my need?

You're going about this the wrong way.
You don't calculate the pps, as it's constantly varying value.

I can't see what units of torque your chart is using. And the chart is made using 1/2 stepping, and your drive is 1/10 stepping, so the chart may not be accurate for your use.

Let's try to explain.

PPS is step pulses per second.
You have a 1/10 microstep drive, so your stepper needs 2000 pulses per revolution.
When your stepper is not spinning, it uses 0 PPS, and has full holding torque. As RPM's increase, the holding torque decreases.
At 100 rpm, your control will be sending 100*2000/60=3333.333 PPS. With 1/2 stepping, like the chart, at 100 rpm it would be 666.66 PPS.

What you want to do is convert the PPS in the chart to RPM. 1 RPM = 6.666 pulses per second.
You need to calculate the maximum rpm you'll be using, and multiply it by 6.666 pps to find the torque available at that rpm. Then see if it will be enough for your application.

Ger21, thanks for trying to explain myself.

If the text not to be very easy to understand is because I use google translator.

One more question for me finally understand.
Based on the file that I have attached in the previous answer, let's assume I'm going to need to fire the 600rpm engine and the firing mode driver be in half-step "with which the motor torque will be and in what part of the graph will be?
