Yes, it has silk screened names. Its a totally isolated thing on the VFD side. The vfd should have a common, a nominally 12 volt plus source when measured to the common. The fwd and rev signals are separated by the spinx1, and generally on the VFD side respond to a closure to this common to enable it to respond to the voltage from the "arm" of the potentiometer. On the computer side, you will need to dedicate on pin of the BoB as an enable signal and wire it up in the hal file. You will need, if using the mesa cards, something that faintly resembles this to get the LCNC speed signal hooked to the spinx1: ############################################################## # Hook pwmgen.00 to the spindle speed and set for PDM output # ############################################################## setp hm2_[HOSTMOT2](BOARD).0.pwmgen.00.scale [SPINDLE_9]PWMGEN_S_SCALE setp hm2_[HOSTMOT2](BOARD).0.pwmgen.pwm_frequency [SPINDLE_9]PWMGEN_S_FREQ #setp hm2_[HOSTMOT2](BOARD).0.pwmgen.pwm_freq [SPINDLE_9]PWMGEN_S_FREQ setp hm2_[HOSTMOT2](BOARD).0.pwmgen.00.output-type [SPINDLE_9]PWMGEN_OUTPUT_TYPE setp hm2_[HOSTMOT2](BOARD).0.pwmgen.pdm_frequency [SPINDLE_9]PDMGEN_PDM_FREQUENCY The data being referred in the right hand argument to needs assigned in the [SPINDLE_9] section of your .ini file. Now, I don't see below, what breakout you are using so I'll just copy and paste from my setup. Keep in mind that these will NOT match yours, but will show you approximately what you need. First, setup the enable signal which in my case uses a gpio pin in my 7i90 card. First, you need to set the output pins for all axis's used as inverting and true low, # Turn pulses to true low, opendrain so they are closures to ground. # stepgen 00 setp hm2_[HOSTMOT2](BOARD).0.gpio.000.invert_output 1 setp hm2_[HOSTMOT2](BOARD).0.gpio.000.is_opendrain 1 setp hm2_[HOSTMOT2](BOARD).0.gpio.001.invert_output 1 setp hm2_[HOSTMOT2](BOARD).0.gpio.001.is_opendrain 1 # stepgen 01 setp hm2_[HOSTMOT2](BOARD).0.gpio.002.invert_output 1 setp hm2_[HOSTMOT2](BOARD).0.gpio.002.is_opendrain 1 setp hm2_[HOSTMOT2](BOARD).0.gpio.003.invert_output 1 setp hm2_[HOSTMOT2](BOARD).0.gpio.003.is_opendrain 1 # stepgen 03 setp hm2_[HOSTMOT2](BOARD).0.gpio.018.invert_output 1 setp hm2_[HOSTMOT2](BOARD).0.gpio.018.is_opendrain 1 setp hm2_[HOSTMOT2](BOARD).0.gpio.019.invert_output 1 setp hm2_[HOSTMOT2](BOARD).0.gpio.019.is_opendrain 1 # the above gpio numbers correspond to the outputs of the canned code in the FPGA's installed firmware for the stepgens I use, and the PDM signal from the pwmgen module in the cards firmware. And the reason I keep calling it PDM is that is a ditherless method of getting quite smooth speed signals from a basically digital circuit. That is done as the modules are enabled in the .ini file by a line grouping like this: [SPINDLE_9] # 16.6 is close to 100 revs per click in low belt position PWMGEN_S_SCALE = 16.6 # make it run in PDM mode, is self smoothing then PWMGEN_S_FREQ = 1 PWMGEN_OUTPUT_TYPE = 3 PDMGEN_PDM_FREQUENCY = 10000 # the SCALE above sets it to run the spindle at 100 rpm per click on the + button, when the backgear is not engaged and the belt is in the lowest speed grooves of the pulleys. All of these settings are of course your personal choices. PDM_FREQUENCY is a balance between update rate and quantization of the speed change. A lower frequency is higher resolution but it should be fast enough so the motor speed doesn't ripple. 10000 is a good choice for me with my fake vfd.. sets emcmot.00.enable FALSE net emcmot.00.enable <= joint.0.amp-enable-out net emcmot.00.enable => hm2_[HOSTMOT2](BOARD).0.stepgen.03.enable Thats not all of that stuff, but you'll get the idea. A gpio pin is an input unless told otherwise, and all signals are closures to ground, with 5 volts fed to the + terminals on the axis motor drivers, with your step/dirs connected to the - terminal on the drivers control plug. ################################################################################# # Setup vfd drive enable yadda yadda, building down from top down forward first # # The SpinX1 only needs pwm and dir I thought, but needs an ena(ble) too. ################################################################################# # start with SpinX1's dir which has to be converted to an output of the correct polarity setp hm2_[HOSTMOT2](BOARD).0.gpio.071.is_output 1 setp hm2_[HOSTMOT2](BOARD).0.gpio.071.invert_output 1 setp hm2_[HOSTMOT2](BOARD).0.gpio.071.is_opendrain 1 # this is the green jumper wire from the SpinX1's FWD, to 7i90-p3-47 net reverse_vfd <= motion.spindle-reverse => hm2_[HOSTMOT2](BOARD).0.gpio.071.out # and the spinX1 does need an enable, so setup gpio.070 for that setp hm2_[HOSTMOT2](BOARD).0.gpio.070.is_output 1 setp hm2_[HOSTMOT2](BOARD).0.gpio.070.invert_output 1 setp hm2_[HOSTMOT2](BOARD).0.gpio.070.is_opendrain 1 # net line moved to be combined with enable_vfd below net enable_vfd <= motion.spindle-on net enable_vfd => hm2_[HOSTMOT2](BOARD).0.pwmgen.00.enable net enable_vfd => hm2_[HOSTMOT2](BOARD).0.gpio.070.out The above demonstrates then when a "net" signal is defined, the next argument on that line becomes the source for that signal. The next two lines show where that signal is to be sent. IF they are in the sequence shown, the => and <= gismo's are optional. Currently, do NOT put a comment as a trailing #comment, put it on its own line. ########################################################### # make the vfd's pdm drive unidirectional, fwd/rev handles that # # but the SpinX1 needs a DIR, which is on P1-43 ########################################################### net spindle-vel-cmd-rps <= motion.spindle-speed-out-rps net spindle-vel-cmd-rps => spindle-abs.in # this come out on P1-41 as the pulse Duration Modulated signal to the SpinX1, red jumper net spindle-unispeed <= spindle-abs.out => hm2_[HOSTMOT2](BOARD).0.pwmgen.00.value This is, without a doubt, incomplete, but with the halmeters help, you should see whats missing.
