PWM not working - 7i96

As above I seem to have lost my spindle speed control keys. HAL and INI attached for reference.

Thanks Jools

Seemed top have sorted it

did a PNC conf for a 7176e and compared them and added this below.

net spindle-vel-cmd-rps <= spindle.0.speed-out-rps
net spindle-vel-cmd-rps-abs <= spindle.0.speed-out-rps-abs
net spindle-vel-cmd-rpm <= spindle.0.speed-out
net spindle-vel-cmd-rpm-abs <= spindle.0.speed-out-abs
net spindle-enable <= spindle.0.on
net spindle-cw <= spindle.0.forward
net spindle-ccw <= spindle.0.reverse
net spindle-brake <= spindle.0.brake
net spindle-revs => spindle.0.revs
net spindle-at-speed => spindle.0.at-speed
net spindle-vel-fb-rps => spindle.0.speed-in
net spindle-index-enable <=> spindle.0.index-enable

This made the buttons show up so will try further. Might not need all of those though so if I don't please let me know.

1 thought. My spindle is PWM driven so do I need the spindle-vel commands? My .ini already has the below:
setp hm2_7i96.0.pwmgen.00.output-type 1
setp hm2_7i96.0.pwmgen.00.scale [SPINDLE]MAX_RPM
setp hm2_7i96.0.pwmgen.pwm_frequency [SPINDLE]PWM_FREQUENCY

with those added I can click the buttons to start the spindle but the PWM output from the 7i96 doesn't waver from -5v.

Any thoughts?

Jools

AXIS decides to show the spindle buttons by looking to see if a signal is connected to a certain pin ( I forget which one logically spinde.0.on)
You have connected a signal to these pins but not connected the signal to a corresponding pin. Ie a driver pin to a signal to a driven pin.

Ie spindle.0.on will be set true by AXIS so the signal spindle-enable will go true but
that signal goes nowhere.

Surely the 7i96 configuration program can connect the pins for you.

Hi Chris

That’s what I thought, but unless I’m doing something wrong on the hardware end I’m at a loss.

I set this up with the 7i96 configuration tool and it produced the first attached ini and Hal flies but no buttons. Researching this and comparing it with a fake pncconf setup for a 7i76 gave me the idea I need to Hal net commands but it still seems not to work.

I’ll investigate the hardware end and try some more settings today but with Hal I’m guessing; I grasp the concept loosely but when it comes to details I don’t have the skills.

Any more help from anyone would be great.
