speed control of shunt motor using labview interfaced with arduino

[Taurai213]

I'm trying to control the speed of a shunt motor using LabView with PID interfaced with Arduino which is connected to the tachogenerator sensor of the motor anyone offer any advice  I have a voltage divider for the sensor to Arduino as is max out is 5v and the sensor is 2v/1000rpm. the motor is being powered by a three phase power panel and a thyristor panel

Very pretty picture, showing "real wires".  Do the orange ones have double-precision voltages, and the green ones TTL Boolean signals?

You didn't ask any question, and didn't provide any code (no pictures, please, just the VIs) for us to examine.  I hope it is all working for you ...

Hi Bob there are no orange wires, the green are small voltage wires, thank you. The three phase and thyristor panel with a rectifying circuit (green cables) run the motor (150v DC 300w 300rpm) with a speed dial connecting to the firing circuit on the thyristor panel.

what I want to ask is how can i go about connecting the tachogenerator sensor, I made a 2 wired cable connected to the motor and the speed dial into arduino, will I need code if I'm using LabVIEW ? Is a voltage divider enough ? sadly I have had to start again my laptop crashed last week now I have a slow one which is having problems updating the drivers for arduino. I'll upload the VI soon as I can. I am knew to this so any help will be much appritiated

here is the vi that i`m trying to use
