the 21x3 cards work really well
just remember you need to price in the i/o daughter card etc when you purchase it
you are limited to 56 i/o on the 21x3 series but im sure this will be enough for a mill

for $800 i think i might put up with a tiny backlash.

to see if the vfd will be suitable for rigid tapping try this.
connect it to an axis (x y z etc)
set the pid up in the galil for the vfd and see how accurate you can get it to move as an axis following its encoder count

thats how its supposed to work.
it needs to catch up it goes faster.
getting ahead it goes slower.
but its done at extemely small increments (0.0003volts)
as long as it has acceleration set fast  in the drive it should be instantaneous.
check what the acceleration is set at in the drive, deceleration also.

is the analogue to the vfd on the speed or torque input?

if you want to do rigid tapping you may have to hook the spindle to another axis too, switched on only for rigid tapping. that way it could be interpolated, unless the interpolating axis is geared to move following the encoder count of the spindle? not sure which method would be recommended. is there a z pulse available on the spindle encoder for a timing mark?
wish i had a mill to try this out!

with mach on and commanding a spindle rotate. ie m3 s5000 etc
open smarterm
use tools/ view data record
check motor shows as on.
with my 2280 i had to send command she using the notifyplugins feature in mach.
for some reason the plugin just wouldnt turn it on. that was my work around. added to my m3 script
also added to m5   moe  ofe=0 to turn it off

do you have the run command ( fwd) being sent as an output to allow the vfd to go into run mode- should show run light on yaskawa drive.

you should be able to set the yaskawa to +/-10v in its parameters. have you fully checked its manual? yaskawa are normally pretty comprehensive in what they can do
if it was rigid tapping before it should be able to do it again!
have you tried applying a small reverse voltage to it? see if it runs reversed?

just had a look at your changer macro... a bit long winded but heh if it works dont fix it.

one thing wortyh adding if your in a waiting loop is a get out clause.
start the loop with

if isestop() then
end
end if

that way if your switch never closes your macro can be stopped instantly by pressing estop rather than constantly looping and freezing mach up.
also worth adding sleep(10) after commands to ensure they get used and not overlooked-gives mach more processing time while in macro too.

after any motion command use

while ismoving()
sleep(10)
wend
to ensure they complete before anything else happens

hope those few pointers help

i just wrote macro for this

use something like this

maxtool=24
if tool<1 or tool>maxtool then
message"tool number not available"
end
end if

also grab tool diameter and height from tool table and check these are not 0.

everything is in mach already to run a spindle!
just wire it to motor command output.

use the spindle speed button on screen to operate or m3 m5 commands in gcode. set speed on screen or through g code

you only need macros if you need to physically automatically change gears etc or run from external buttons
i use the analogue inputs on galil to give me load, max load readings on the screen too (requires a small macro) something to do when the machine is up and running ok.
