Teco 7300 CV

Thank you, I will check out Littlemachineshop, we are neighbors with them, same business park.
 
On the display it's printed HZ/RPM, so it should show RPM too, no?
I managed to play with the 4-04 setting(display scaling) and the blinking has stopped.
I will have to bring my own (car)tachometer to test out the RPMs with it. The machine is at my workplace.
 
I think you are right. I think the manual refers to rpm as line speed with the factory default at 1800. I have no idea on how to program that right now so good luck. The reason I was looking at a separate tachometer is all my machines are belt driven with multiple sheaves so the actual motor speed which the vfd should know is not the spindle speed which is what the tooling cares about.
hope this help

We have one of those at work and we have a flashlight style strobe too, but to me they don't seem that they show the right RPM. The tachometer one varies a lot the RPM and the strobe one it's way to much off. It can't multiply either.
 
OK, finally I have managed to make it work and it shows the RPM.
I have used a laser tachometer(Unit-T), with the belt on the third pulley from the top. The spindle was showing 1847 RPM and this number I have inserted in the 4-04(Display scaling 0-999) and with the potentiometer AIN Gain(7-00) at 100%.
I haven't done any heavy cutting yet, but it seems like it's working properly.
Most of the parts were purchased from factorymation.com, except the metal case.
Here are some pictures:
