[FluidNC Issue#1434] 10 volts inoperative output (spindle )

#1 – MitchBradley 于 2025-01-21

There is not enough information for us to help. “no message when start to run” does not tell us which user interface program or sender you are using when looking for messages, so we cannot guess what might be wrong with your setup. Please tell us exactly what you did to get this far. Give us a lot of details.

#2 – bdring 于 2025-01-21

I saw your video. It is clear that something is not set up right. The io.13 LED and either the io.14 or io.15 LEDs should be lit.

How are you turning on the spindle?

You should be sending the M3S24000 gcode line from the console.

You can get the startup messages by sending $SS at the console as described in the problem report template.

je vais voir pour la ligne de code m3S24000 et pour le message de démarrage, pour le moment voici mes constatations et mes connections … je n’arrive pas à avoir 10 volts sur votre carte… la led io.13 qui correspond à ma config FluidNc…. output_pin: gpio.13 n’est jamais allumée…
J’ai avec m3 ou m4 les leds io.15 et io.14 qui s’allument (forwardpin: gpio.15 reversepin: gpio.14) et io.12 pour le liquide de refroidissement (mist_pin: gpio.12)….
J’ai un VDF YL620 branché comme suit : carte vers VDF…. io.14/Rev… io.15/Fwd… io.13/10v… Gnd/Gnd…
j’ai reglé également les parametres de mon VDF comme suit :
P00.01 sur 1
P07.08 sur 3

#4 – MitchBradley 于 2025-01-21

Please tell us what action you are performing, using what user interface program, in order to try and make the 10V signal go active. You said “je n’arrive pas à avoir 10 volts” but you did not say what you did in order to ask FluidNC to make that signal go active.

#5 – bdring 于 2025-01-21

I cannot help you until I see the startup messages. There could be an error in your configuration file. I don’t know if the configuration file is loaded.

What interface software are you using. The FluidNC WebUI, a gcode sender, FluidTerm? Can you connect a basic serial terminal to the controller?

I installed FluidNc on the PCB following the video ( https://www.youtube.com/watch?v=NxfWvtqhs1M&t=268s )

from 4min30 to 9minutes then 11.19min to 18.20 minutes…with Rapid Change ATC + WebUi…etc…

and in my config here is the part declared for 10 volts:10V:

forward_pin: gpio.15
reverse_pin: gpio.14
pwm_hz: 5000
output_pin: gpio.13
enablepin: NOPIN
directionpin: NOPIN
disablewiths0: false
s0withdisable: true
spinup_ms: 0
spindown_ms: 0
tool_num: 0
speed_map: 0=0.000% 6000=25%.000 12000=50.000% 24000=100.000%
offonalarm: true

#7 – DVA85 于 2025-01-22

but I don’t understand why the 10 volts is not at the output for the spindle… especially since m3 lights up then m4… should this open the “relay” to send 10 v??
For the rest everything works correctly… homing, 3.3v, 5v, movements of the X, Y, Y1, Z axes according to the motor 1, motor 2, motor 3, motor 4 outputs… and so my config.yaml takes this into account….
Is the 10 v correctly declared in my config.yaml??

#8 – bdring 于 2025-01-22

Please send me the startup messages.

Measure the voltage with the wires disconnected from the vfd.

What happens to the voltage when you send m3s6000, the m3s12000, then m3s24000

#9 – bdring 于 2025-01-22

Can you show the connections on the VFD?

#10 – DVA85 于 2025-01-22

results of my tests…
m3s6000=3.5v
m3s12000=5.7v
m3s24000=10.27v

same voltages for m4s6000, s12000, s24000

same voltage without wires connected

m5 off io.13

$ss ( see video )

VDF connection ( see photo )

i get a video for $ss but i don’ t know how to send on github….

#11 – MitchBradley 于 2025-01-22

You have it connected wrong.

!Image

V10 is an output from the VFD. You need to connect the FluidNC 0-10V signal to the adjacent VI1 VFD input

#12 – MitchBradley 于 2025-01-22

You might also need a wire from FluidNC GND to VFD XGND . The existing wire to VFD GND is for the analog 0-10V signal. It might possibly work for the digital FWD and REV signals too, but it is better to have a separate one.

#13 – DVA85 于 2025-01-22

ok for this, i understand…i wire from Pcb GND/XGND ( VFD) and 0-10v signal from Pcb to VI 1….but do i need to change parameters of my VFD ?

Basic settings VFD……P00.01 = 0, P07.08= 0 but i read others settings on 620 YL…

do i need change with P00.01=1 and P07.08=3

P00.01
Start / stop command source

0: Operator VFD Front panel button

1: From external input (X1-X6); (VFD Stop
Button enabled)

2: From external input (X1-X6); (VFD Stop
Button disabled)

3:From Serial (Modbus Rs485)

4:By user application program control
Electric machinery

P07.08
Frequency 1 select method

0: Operator VFD Front Panel (parameter:
P03.06) 0 0 0

1: Pre-set Freq, P00.01 Set frequency
value ,Operation panel keyboard,Can be
set directly

2:No. X paragraph frequency

3: Analog Input. :(P03.10-P03.13)

4: external simulation amount 2 (VI2)

5: (Modbus Rs485) Given frequency

6: User application program, given
frequency

7:( Pid)Output frequency

thank’s a lot…

>do i need change with P00.01=1 and P07.08=3

yes

#15 – DVA85 于 2025-01-22

than’s a lot i’ll try this and i’ll come back to you…

#16 – bdring 于 2025-01-22

Let me make a better drawing for you. You may have damaged the controller by connecting to the 10V terminal.

Do all measurements I asked for with all wires to the VDF removed.

#17 – DVA85 于 2025-01-22

the VFD responds normally if I keep the control board, so I changed the settings…I don’t think it was damaged…

latest tests…with connections (photo)

m3s6000….Forward lights up on the control panel (VFD)
m5 extinction io.13
m4s6000….Reverse lights up on the control panel (VFD)
m5 extinction io.13

but the spindle does not turn despite
P00.01 = 1
P07.08 = 3

but I don’t know what parameter to change in my VFD settings….

#20 – bdring 于 2025-01-22

Before you connect to the VFD. What are the voltages with

M3S6000
M3S1200
M3S24000

#21 – DVA85 于 2025-01-22

i think i understand the reason why the spindle stay off…

I understand your connection…for mine it is missing the GREY cable which goes from the common (fluidNc card) to XGND (Vfd) and therefore removed my bridge between GND/Fwd/Rev Com (FluidNc card)…I think that will completely resolve my search…I will keep you informed on Sunday…thank you very much

#22 – bdring 于 2025-01-22

Hopefully connecting the 10V output on the controller to the 10V output on the VFD did not damage the opamp on the controller.

#23 – DVA85 于 2025-01-26

Results…no spindle start despite wiring with Com/XGND as in your photo…and the following parameters, P00.01 to 1 and
P07.08 to 3…….also on “on” the 1st white pin of the red square module above the green strip or the 4 pins on “off” …

I don’t see which parameter to change on my Vfd or how to test the 10 volts of the Vfd………..

in manual the vfd dashboard responds and the spindle turns………..

the card responds well too…

I’m a bit short of solutions…..

#24 – bdring 于 2025-01-26

If the io.13 LED on the controller lights up with the M3S24000 command and you do not have any voltage on the 10v output pin of the controller, you probably broke the circuit on the controller by shorting it to the wrong pin on the VFD.

#25 – MitchBradley 于 2025-01-26

You can test the VFD without FluidNC by connecting a potentiometer on the GND, VI1 and V10 pins. Most VFD manuals have a diagram showing that wiring. If wired correctly and the VFD parameters are set correctly, turning that potentiometer knob will change the VFD speed, although you might also need to press the run button.

#26 – DVA85 于 2025-01-26

j’ai bien la Led io.13 qui s’allume, et j’ai également sur la Pcb les voltages en fonction de la demande S6000, S12000, S24000…
le voltage va de 5.5v à 10.5 volts en sortie Pcb 0-10 v…
mais par controleur tu veux dire du Vfd…? Dans ce cas je dois tester la sortie 10 volts du VFD ?? est-ce correct ?

#27 – DVA85 于 2025-01-30

Great everything works perfectly… if it can help here are my parameters for my VFD YL 620…
P00.00 = 400 ( fq 400 hz )
P00.01 = 1
P07.08 = 3
P03.12 = 100 ( fq mini )
P03.13 = 400 ( fq maxi )
for the white dip switches in the red module above the green strip you have to put on “on” the 2 and the 4 (activation 10 volts of the Vfd) and leave on “off” the 1 and the 3…

The wiring is correct with the configuration below…

A big thank you to all ….Phil
