Status Word 1 it is Status Word.
Status Word contains information about the state of the inverter and motor.
1. Use Starter software
2. Find r0052 parameter
3. You will see what mean all bits |

r0022 Act. rotor speed
Displays calculated rotor speed based on inverter output frequency [Hz] x 120 / number of poles.
Being a calculated value by the mathematical tip of the motor has nothing to do with parametrization and status words sent and received by USS to MM4xx. |

Hi ygor. I think the right equation is: (2 x pi x f)/p.
f can be 50 Hz or 60 Hz for some different countries.
may i right or wrong ???
can you tell me how Micrormater calculated many values of Motor ???
i tried to calculated many equations about 3 phase motor, but i still don't carry out.
