Spindle Tacho Dro for CNC4PC
« on: April 22, 2012, 05:53:43 PM »
Using a CNC4PC i/o board and a Mitsibushi Fr-D720S inverter with a 400hz spindle motor,
Can anyone point me in the right direction if they have added a tacho to the chinese spindles to give an acurate readout of spindle RPM on a DRO.
Do I need modbus? smoothstepper? etc

Thanks

George.
