Here you go, interesting , it would appear that pressing the spindle
button with no speed selected float out jumps to 5.555556e-05 ??
Not sure about the actual difference in CW/CCW motor speeds, may just be
the motor prefers running in one direction and I think I can tune that
in the VFD itself.
At idle without spindle enabled
r...@steve-desktop:/home/steve# halcmd show param pwmgen
Parameters:
Owner Type Dir Value Name
13 s32 RO 110 pwmgen.make-pulses.time
13 s32 RW 17866 pwmgen.make-pulses.tmax
13 s32 RO 565 pwmgen.update.time

13 float I/O 0 pwmgen.0.pwm-freq
13 float I/O 18000 pwmgen.0.scale
13 float IN 0 pwmgen.0.value <== spindle-abs-cmd
Pressed Spindle CW (F9) - No speed set, but spinlde turns at 500 rpm or
so.

13 float I/O 0 pwmgen.0.pwm-freq
13 float I/O 18000 pwmgen.0.scale
13 float IN 1 pwmgen.0.value <== spindle-abs-cmd
Pressed CCW (F10) - No speed set spindle turns at 500rpm or so.
Pressing spindle slower (F11) has no effect.
r...@steve-desktop:/home/steve# halcmd show pin pwmgen
Component Pins:
Owner Type Dir Value Name

13 float IN 1 pwmgen.0.value <== spindle-abs-cmd
Then pressed spindle faster (F12) - spindle slows to 50rpm or so.
