Servo Tuning FF

No (you cannot because the pin is "owned" by the PWM gens) but you cannot wire ENA 0 to spindle enable or you will turns off the other analog outs when the spindle is off

I suppose the question is what the hm2 driver pwmgen enable pins do then, as there seems to be one for each pwmgen. It might just set the pwm duty cycle individually to zero.

It's an easy test, though, to turn the spindle on and see if the axes wake up.

net spindle-enable => hm2_5i23.0.pwmgen.00.enable
is the error

Pete,

I changed the enable to be fired from an ladder relay off of my main machine power, but im not seeing anything yet. How do I go about bypassing the PID function, I have already #'ed out all lines in my hal relating to PID,FF, Gain, Bias?

The simplest would be to type the following in the command box in Halconfig (which might actually have disappeared off the bottom of the window, try resizing the window)

unlinkp hm2_5i23.0.pwmgen.02.value
unlinkp hm2_5i23.0.pwmgen.02.enable
setp hm2_5i23.0.pwmgen.02.enable 1
setp hm2_5i23.0.pwmgen.02.value 0.1

(and so on)

I finally got it to work and show voltage on my meter. Now its time to go back to yesterday and get to putting some power to the drives.

I had to go back to the original 02 and 04 pwmgen enable lines and connect them back to the PID ENABLE output, with the 00 enable still fired from my main power ladder rung.

See where we go from here.

Thanks again for all the help from you guys,

Rick

Also note you also will want
setp hm2_5i23.0.pwmgen.00.enable 1
since pwm enable 0 is a global hardware analog out enable
