That I'll try again. but setting it to 2 desensitizes the tach reading, 2 makes s6000 into 400HZ, which the tach says is 6k. 04 is off by 2/1 so s12k is 400 hz, and we both know 08 is a lie. But I'll try it anyway. But didn't, tried -S24000 on the option line, which made it all correct so an s24000m3 in the mdi works, as does an s6000. Getting closer, now need to figure out why the tach is zeroed instantly my an m5 cmd while the spindle-speed-fb is still coasting to a stop. Tach is fed by: net spindle-abs-fb <= hy_vfd.spindle-speed-fb => pyvcp.spindle_rpm So it should follow in real time. Letting the vfd handle rev/fwd. Thanks Andy.
