[Emc-users] Analog spindle control HM2
Hello group! I have set up a retrofit 3 axis milling machine with mesa 5i20+7i33+2x7i37 The 3 axes are configured, tuned and works great. Now I want to use the fourth channel on the 7i33 to drive my freq inv. spindle I need a spindle enable signal and a 0-10v signal. In the wiki I found Analog spindle speed control using Mesa 5i20, but this is old stuff not using HM2 driver, and it looks like this: # Set up spindle speed net SpindleOn motion.spindle-on net spindle-rpm-cmd motion.spindle-speed-out setp m5i20.0.dac-03-gain [SPINDLE]DAC_SCALE linksp SpindleOn = m5i20.0.dac-03-enable linksp spindle-rpm-cmd = m5i20.0.dac-03-value setp m5i20.0.dac-03-offset 80 Can somebody help me to put together the right hal code to work with HM2? I have searched the wiki and forums, but cant find it anywhere. Best Regards! Lars Levin -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.

Lars Levin you will need to run the spindle command out through an ABS to make it always be a posative value (emc outputs a - speed value for m03) then you will have a 0-10v signal for the dac out u may have to reverse the output on the card chanel if its 0- -10v here is my code for my spindle #invert voltage out setp hm2_[HOSTMOT2](BOARD).0.gpio.XXX.invert_output true setp hm2_[HOSTMOT2](BOARD).0.pwmgen.XX.output-type 3 #make spindle pos loadrt abs count=0 #scale spindle speed to volts loadrt scale count=0 addf abs.0 servo-thread addf scale.0 servo-thread #spindle speed gain #hm2 1=10v out #pwm/speed=1/6000rpm=0.0001667 #6k setp scale.0.gain 0.00017 net spindle-abs abs.0.in = motion.spindle-speed-out net spindle-abs-out abs.0.out = scale.0.in net spindle-out scale.0.out = hm2_[HOSTMOT2](BOARD).0.pwmgen.03.value then just link spindle forward, spindle reverse to the IOs you need. this should work i just typed it up quickly for you. rob -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.
