Mach4 General Discussion / Re: Mach4, C11 BOB, & Huanyang VFD - how to control spindle?

« on: December 04, 2016, 11:43:57 PM »

I changed the pin mappings in ESS Output Signals for Spindle On - maps to Pin 16, which causes relay to close and connect DCM to FOR, and the spindle starts. I think I've gotten closer, now to figure out how to scale the voltage from 0-10 to correspond to speed.

thanks again for the help

Thanks for help so far, but I still CANNOT get the machine running.

If I hook a 9v battery from ACM to VI and then jumper DCM to FOR, then the spindle spins perfectly. It spools up to 400 hz very nicely. As for Mach4, well it's still being a PITA and won't control it.

I want to use Pin16 (which is a relay out on my BOB) for my FOR-DCM, and Pin 14, which is an analog output to control speed. I dont think I'm wrong on this, and it all makes sense in my head, but Mach seems like one of the most unintuitive programs to configure in the world.

When I click spindleCW in Mach4 (M03) I want the spindle to TURN ON. It won't do this. I have wires from v_in and NO (normally open) from the relay on Pin 16 connected. How do I make Mach4 close said relay when M03 or the button is enabled? I've tried every mapping I can dream of through ESS and it doesnt work active high, active low, or anything else in the middle.

I'm at my wits end here and don't know where to turn. Mach4 and ESS just seem impossible to configure, and from an intuitive sense I understand exactly what I'm trying to do.

Could you screenshot that schematic?

So pardon my ignorance, but I'm literally at wit's end on this board, and what you said only served to complicate things. There are 2 ACM's on the board, and I've already told the VFD via a jumper that I'm going to use voltage input instead of 0-20ma current input.

So here's what I think is right:
FOR SPEED CONTROL
Breakout Board                              VFD
Analog Output Ground - - - - - - - - ACM (next to AI/VI on lower level of VFD)
Analog Output 10v --  - - - - - - - - -VI - this is the 0-10v signal that I'm able to control via speed in Mach4


Does the attached wiring diagram look plausible?

Got it. I adjusted pot output to max 10v. However, I don't know which wires to connect to the VFD. See my original post for the pics of the VFD and output from breakout board.

I'm still unsure on what connections from my breakout board need to be made to the VFD. Additionally, what do the Mach4 configuration settings need to be for my frequencies?

I've now gotten voltage on pin 14. My base PWM frequency is 1000hz, the ESS Base frequency is 25hz, and when I command different spindle speeds in Mach4, my voltmeter picks up voltages from 0-7 volts. I can't get it to go to 10v at 18000 RPM.

I am not getting 0-10v. It must be a Mach setting that's wrong. VFD is configured for external by configuring Parameter 0001 for external.

I think I'm losing my mind. I've been over hundreds of forum posts and tried every conceivable configuration of Mach4 I can find. I cannot figure out this VFD.

I have a 3 KW Spindle , 
Huanyang 3 KW VFD, a C11 Breakout Board and an  Ethernet SmoothStepper

ESS Plugins are enabled and XYZ, homing, and everything else works. I can control the relays on the BOB, but I can't get Mach4 to control the spindle. Spindle works, I was able to manually control it from the VFD with it completely disconnected.

Here's pics of the breakout board (I'm assuming I'm supposed to be using pin 14 and 16, one for direction/enable and one for a 0-10v analog output for speed control) as well as the input to the VFD.

I have the spindle configured in ESS as PWM, although I've tried step/dir, and relay. Pin 14 is my 0-10v analog output, and pin 16 is a relay to control enabling/direction.

I realize you can't trace the wire connectivity in the pictures, but where am I off on this? What needs to connect where, and what should my Mach4 settings be?

thanks in advance

Yeah that works, but not in reality. The text is like 800 micrometers tall and is barely legible a couple inches from the screen.  I think I can make it work for initial setup at least.

Nope, first column is not width configurable. I wish it were that easy.
