i can send you install files by mail if you want

Thanks for the suggestion.
But in new versions there are a lot of useful changes that make work much easier.
In addition, it is not a question of changing the value of parameter 416.
It can be changed. But at a certain value of it, there is a breakdown of the STEP signal generation. Read the article.

ok you think i wille be install this last firmware? where download?

While Ytliu tries (or does not try) to implement the delay of DIR-STEP programmatically, I'll try to ...

Looking forward to your results. In addition, I have completed the logic design, the test results are satisfactory, #416 set to 7000ns can meet most of the drive requirements. Thank you again for your excellent work.

Excuse me Ytliu.
I confess, I doubted your ability to solve the problem.
But your abilities, as always, exceed all expectations.

In any case, I will bring the digital delay line to practical implementation.
If you, for whatever reason, fail, the digital delay line will be a temporary solution to the problem.

Dear nikolay / ytliu
Please, I need your helps.I will order Leadshine HBS86H cloosed loop step driver. Do you have any
experience for this driver? In the manual of driver, there are some technical notes. But, I don't want a problem like step lose. DDCSV 2.1 and HSB86H driver matching perfectly ?

-  power supply capacity? Which one is the good for the controller? In the table ;  60VDC 10mA  / 100VDC 16mA
-  In the manual, PUL/DIR notes: "Double pulse mode (CW/CCW) Software configuable" ? is it a problem for ddcsv 2.1? You are talking  a problem about CCW/CW.
-  R=0 if VCC=5 , I am not sure, Should I add resistor between controller-driver  or remove series resistor (101=100 ohm) form controller? or nothing.

I will be pleased if you help me

Your problem is that you think too much.
And you complicate the task too much.
You have an NC machine tool of an amateur class. Why do you need a stepper motor with an encoder?
Why such a powerful driver?
I do not know what country you are from. Maybe there you have all the millionaires and you just do not know where to spend money?
If I'm wrong and you are not a millionaire, buy cheap drivers, like DM556.
To him buy ordinary cheap stepper motors for 3 amperes.
Everything will work. I guarantee this.
Unless, of course, you do not sell defective parts :-)
If I'm not mistaken, and you're a millionaire, buy brushless servo motors.
They will be in all respects better than stepper motors with an encoder.

All of machine parts are second hand ; stepper motors (nema 34 with encoder) , vfd , screws +nuts , etc. I am not millionaire

Then take any Leadshine driver with the encoder.
Lichuan drivers are copies of Leadshine. Kind of like Adidas and Abibas :-)
You can take the driver without the encoder. The motor encoder is not necessary to connect.
Everything should work if the drivers are not defective.
Do not think about it that much.
