Hi

I am setting up my Huanyang HY02D223B and spindle and I have a question I hope you guys can help with. I have the 2.2kw 220v 8.5A 400Hz spindle. I am trying to determine the correct setting for PD143 (No. of motor poles).

Using this formula Ns = 120*f/P

P=120*f/Ns = 120*50Hz/24000rpm gives me a result of 0.25 . which does not make sense!

What have I got wrong?
What is the correct setting for PD143?

Thanks in advance.
