M31 Motion Controller / Re: VFD

« Last post by paul.stephens on March 13, 2026, 11:02:08 AM »

Attached is a quick and dirty wiring diagram. https://es.soyan-tech.com/Content/upload/PDF/20189675/SVD-p-User-Manual.pdf Here is your manual.

When it comes to your VFD, when in analog mode, it looks for 2 things. A forward Command and voltage in DI1 for your "Speed". I would recommend trying to increase that value to something like .1 or .2 to cover any potential residual voltage.

When it comes to tracking cycle time, look up in your upper right hand corner of your screen next to the date and time.

The Current Goal is to have it fully integrated into Mach within the next couple of weeks.

It is set for 0v and there is 0v at A11 when it is turning slow . Is there a job timer on the main screen for the tine it took to run the file , like on Mach4

General Mach Discussion / Digital dream LAN5160T4 upgrade ?

« Last post by gldfshrdr on March 13, 2026, 07:57:25 AM »

HELP! I'm looking for the driver/plugin for Mach3 on the above unit. The seller failed to include the Mach3 CD containing the driver/Mach3 plugin.
 I've had my system running for about 5 years and needed to drive X axis with 2 motors to stop weird angles on my projects. I guess slinging a heavy dewault router on a 1 meter gantry was not a good idea.

Thanks .....dt

Mach4 General Discussion / Out of Band Axis Setup

« Last post by ecapstone on March 12, 2026, 10:55:29 PM »

Hey folks, I'm in the process of setting up a CNC plasma table using Mach4. From the Plasma_Configuration PDF included in the docs folder, I can see that I need to configure the torch height controller to use an Out-of-Band (OB) axis. But, I can't find any documentation elsewhere for how to actually set that up.

My Z axis is configured for motor 2. I've copied those settings to Motor 3:


And I've told Mach4 to use Motor3 as OB1 (axis 6):


And I've configured the THC to use axis 6:


What I can't figure out is: How do I tell Mach4 that motion commands intended for Motor 3 should actually move Motor 2?

This feels like something I might need to configure at the motion controller level (I'm using a PMDX-411, plugged into the PMDX-122 that we used to control the machine with Mach3) but PMDX's forums are down so I can't ask there. Hopefully I'm missing something obvious in Mach4?

Mach4 General Discussion / Re: Mach4 - C82 - PlasmaSensOut - Z axis

What motors do you have mapped to what axis?

Motor0; Not used?
Motor1; Y Axis
Moror2; Z Axis
Motor5; "THC Axis"

Mach4 General Discussion / Re: Mach4 - C82 - PlasmaSensOut - Z axis

Hello
I tried to install Mach4 vs. 5920 and the ESS - 320.
I use the M4_CNC4PC_Plasma_V2 screen
I configured only motor 1 for the Y axis and motor 2 for the Z axis. Signals only step and dir for the motors and limit switch P+ and P- for the end position sensors. Here is the FIRST problem I have.
In manual mode in jogging mode the y axis moves. On the screen I see the change of coordinates and the axis physically moves. On the Z axis I see the change of coordinates on the screen but the z axis does not physically move. If I replace the ESS 320 plugin with the ESS 298 plugin it is the same, the y axis moves and the z axis does not work for me. As for the configuration, I still do not change anything. I upload the ESS 278.1 plugin there in this case the y axis moves as before and physically but at the same time the z axis works and moves physically. If I suddenly put another plugin there, the z axis stops. I don't understand this at all and when I have plugin 278.1 there, the z axis works for me but the THC doesn't work at all, so I wanted to test another plugin.

Speed values are more of a persistent value for Speed commands. If your S value is 0 and your spindle still spins a little, then the VFD further setup.

You can increase the value of P4-13 for the minimum voltage input for a speed command. This will make a bit of a deadband in the case of residual electrical noise. I would set my spindle speed to 0 and then check voltage at AI1 this value should theoretically be zero. If you have voltage there, set P4-13 to the number you see on your multimeter, this will create a deadband from zero to whatever number you insert causing your spindle to stop moving.

When i load Machpro and turn on VFD , my spindle turns very slowly ( 2.37 hz ) , can stop it with vfd stop button
