General Mach Discussion / Re: I need HELP… Please

Dave,

What do you mean it did not help?  What we need is to identify where is the problem coming from.  What exactly did you swap? What happened?

I understand you have one axis that is faulting.  We need to understand what is causing the fault.  You need to swap connections until you identify what is following the fault.  Please swap:
- Cables from the breakout board to the driver.
- Driver to motor (power and encoders).
- Motor on axis, as it could be a mechanical thing with the axis.

I can take a look at your files, but I am not sure there would be anything evident there.

Dave,

I do not think you need any files from me.  The idea is that you swap axes, cables, drivers, etc...  And what what follows the problem.

Let me know how it goes.

Dave,

If you are concluding that it could be something in the breakout board settings, I will presume you have already swapped the cables going from the breakout board to the driver, and the problem stayed with the same axis on the breakout board.

Please confirm this is the case.

Dave,

If the is issue is just with one axis, I would start swapping axis, driver, motors, cables, etc.  until you have singled out the issue.

Here are some thoughts:

- Your driver setup looks fine, but if the motors are the same, I would load the configuration from one of the drivers that are OK.
- Could it be something mechanical with the axis?
- Is the axis is truly faulting? What happens if you move the jumper to HARD ENABLE?

Please check this and let me know how it goes.

PoKeys / Re: How to use Mach and Pokeys to control LED status lights?

« on: July 25, 2013, 10:30:10 AM »

I suggest you make a backup and update Mach3, the pokeys software and plugin, and the firmware.

Life is so much easier than what you are describing now with the current plugin.

General Mach Discussion / Re: Can't get 2.2KW spindle to work

Brett/Mike,

The VFD you are using does not support direction, just start/stop.  The C41 clicks the relay to start when there is a valid PWM present. The relay will close the contact to start the relay.

Here are some thoughts on what could be going on:

- It is important to clarify that when you say the spindle starts, you are confirming if the relay is clicking, that the LED for the relay lights.  so we can see if that the activation does come from the C41, not from a faulty connection.

- Check the wiring: http://cnc4pc.com/Tech_Docs/JINAN2ESS.pdf. Make sure it is exactly like that.  My thinking is that you are using a different common for the connection of step and dir signals or the VFD connections, that is why you see that behavior when you use the multimeter, which closes the contact.  This would also explain why the spindle will start when you close mach3.

Hood,

The C41 is powered with +5vdc.  It has an DC-DC converter built in that generates the isolated +12 that powers the analog circuit.

When using this board with our boards with RJ45 connectors, you just run one CAT5 cable from the breakout board to the board that delivers step, direction and power to the board.  So in these cases an external power supply is not required.

Another thing that can be confusing about these boards is how the relays work, as you do not need to configure relays in mach3, just step and direction.  The board automatically drives the relays based on the step (PWM) and direction signals and the operation mode (International or US).

So for most people this setup is simpler as they have less issues to deal with.  It is just a matter of one CAT5 cable to the breakout board and wiring the VFD, and as far as configuring Mach3, it just a matter of enabling PWM spindle speed control and tuning the spindle axis.

In Mike's case, he is wiring using the terminals.  But the problems he has had wiring this particular board, as there is a wiring diagram for his setup:

http://cnc4pc.com/Tech_Docs/JINAN2ESS.pdf

His problem is with setting PWM spindle speed control.  I understand from his last email that he configured it successful, but there were still some issues with the relays.  I think he has some pin conflicts.

Mike,

No, the C41 does not require an external +12vdc power supply.  We already went through wiring.  It is ok, and you are getting action on the relay, so there are no issues around this.

Please refer to the configuration of the analog output and testing that I have been saying.  The idea is that we confirm the relays and analog output are working like they should before connecting it to the VFD.

I will email you an XML that should work for that, but you will still need to set the pins how you wired it.

I may not monitor this thread any more, please email me.

Mike,

I think the relay is configure ok, it is the analog output that is not getting there.  So the VFD tries to start, but it receives no speed command.

Mike,

You need to verify the voltage on the 0-10vdc terminal.  You should get a voltage that is proportional to the commanded speed. Make sure you set spindle under motor tuning to max velocity and max acceleration and that you set the spindle min and max speeds under pulley setting.
