Like most, I have a Boxford TCL160 lathe.
I'm using the original Inverter drive Mitsibushi Z024-UL
There is no Parameter unit fitted to the inverter so I cannot change any of the settings.
The Chuck is running flat out at 5Vdc and slows proportionally in keeping with the applied Voltage 0 - 5Vdc
Does anyone know what the actual speed of the chuck(Spindle) is at 5Vdc?

I don't know..........
You can buy a nice hand held electronic Chinese tach from Ebay for around $10. The one I bought works great!
