CNC mach spindle not spinning

Hi Bernard, the spindle is a 220v 3 phase spindle and the board is a very basic VFD which converts 220v single phase to 220v 3 phase and allows speed control.
I was under the impression that it worked in manual mode but you wanted to control it using mach3. This changes things slightly because obviously if it doesn't work in manual mode it suggests some thing is wrong and therefore won't work under mach3 control even if it was possible.

So first we need to get it working in manual mode, however this could be easier said than done because it's most likely a parameter setting and without the manual then we are just guessing in the dark. If you have the manual then Zip it up and post or give us a link to it if online.
It could be the switch or a wrong connection so please take pictures of the terminals on the control board so we can see what wires are used. This will also confirm if Mach3 can control it.!

Also take pictures of the other 2 boards but concentrate on wiring and terminals. Try to take the pics so they show the terminals and where they lead, we don't need close up pictures just showing where they lead to and any markings on connectors etc.

You could always use Dropbox for large files.

Hi Jazz, here is the link to the 'User guide for CNC 3040. Hope this will help. I followed this guide.

Why would you use that when it's clearly a completely different control box to what you have.? Just because it's called 3040 doesn't mean they are all the same.!
You need the relevant docs to the control box you have. In any case that type of document wouldn't be any use for checking the VFD parameters or setting it up.

I can't help if you haven't got the Docs because it's not something that can be guessed at.!

I don't know. this was given to me with the purchase. I will have to revert to them. Thanks

Trawl through this thread and see if there's anything of use.
Has the same control box.

Bernard,

The number on the front of the controller display on the main front panel - PRT-E1500 is your search term to find out more on the spindle-controller and set-up instructions. It's not a device I've experience of so I'll butt-out of here, but hopefully someone can offer some useful advice. You might want to source a pdf of the controller manual and find out how to read the program parameters (I wouldn't change any... just yet, but find your way around the interface and read about how the front-panel controls are expected to work). All knowledge is good.

Found this if it helps:

PRT-E1500W VFD SETTINGS for
CNC3020/CNC6040
"I finally figured out the VFD and Mach3 software settings for my 1.5 kW,
110Vac, 400Hz Spindle with the PRT-E1500W VFD in order to run the spindle either
in manual mode or with PWM control through the PC. Here's the procedure I used.
(Note I didn't change the 220V setting to 110V in the VFD since there isn't a
mechanism for generating higher voltage than the VFD supply and it doesn't
appear to be necessary, but this should be vetted by another party
(CHIMERA1960?) prior to long duration running).
1) Reset the VFD to factory settings
a) Set D001 to 1 (may be able to skip this step)
b) Set D176 to 1 and press Func (this resets VFD to factory settings)
2) Reset the VFD to 400Hz max operating frequency rather than the 50Hz default:
a) Set D002 to 400 (need to set this before D000)
b) Set D000 to 400
c) Set D003 to 400
d) Set D009 to 400
e) Set D021 to 400
f) Set D093 to 400
3) Set VFD to receive input frequency setting for spindle throttle control from
the AVI terminal:
a) Set D031 to 1
4) OPTIONAL but I would recommend for additional debug/safety reasons: Set VFD
to allow manual spindle "stop" from terminal even when running from PC
5) OPTIONAL: Set AVI terminal to readout spindle rpm instead of VFD frequency:
a) Set D039 to 1
6) To run the spindle manually with variable speed directly from the AVI
terminal:
a) Set D032 to 0
b) Make sure switch next to AVI terminal is set to "Manually"
b) Use AVI "Pot Dial" to set spindle rpm
c) Use AVI "Run" to start spindle
d) Use AVI "Stop" to stop spindle or turn down Pot Dial to 0
7) To run the spindle from the PC (note the PWM signal from Mach3 adjusts the
setting of the AVI terminal as if it were the VFD Pot. The PWM signal is NOT
going directly to the spindle motor):
a) Make sure you have the right Port/Pin settings in Mach3 (see example
settings below)
b) Set D032 to 1
c) Make sure switch next to PRT is set to "PC"
d) Very important: On Mach3 User Panel, make sure you select and input the max
spindle speed (i.e. 24000).
e) Select the actual spindle speed by adjusting up/down arrows or dragging the
column up/down for relative speed setting changes.
f) Use "Spindle CW F5" button or "F5" to toggle turning the spindle on/of
Mach3 software settings that work for my spindle and wiring configuration (if
you have an issue with the X,Y,Z position controller settings let me know, but I
think most don't have this issue):
A) Ports/Pins
1) Port Setup and Axis Selection
i) Port #1 Enabled
ii) Kernel Speed Set to 35000 Hz (this worked for my 2.9 GHz desktop
controller, but you may need to use the lower 25000 Hz setting for slower
machines)
2) Motor Outputs
i) Spindle Enabled = Active
ii) Spindle Step Pin# = 1
iii) Spindle Dir Pin# = 0
iv) Dir LowActive = Active
v) Step Low Active = Active
vi) Spindle Step Port = 1
vii) Dir Port = 0
3) Input Signals
i) EStop Enabled = Active
ii) EStop Port = 1
iii) EStop Pin Number = 10
iv) EStop Active Low = Active
v) EStop Emulated = Inactive
4) Output Signals
i) Enable1 Enabled = Active
ii) Enable1 Port# = 1
iii) Enable1 Pin Number = 14
iv) Enable1 Active Low = Active or Inactive
iv) Output#1 Enabled = Active
v) Output#1 Port# = 1
vi) Output#1 Pin Number = 17 (this should NOT be the Motor Output Step Pin
(e.g. Pin #1 in my configuration) as may be indicated in some of the user
manuals)
vii) Output#1 Active Low = Inactive (important to make sure Spindle is On when
Mach3 Toggle Switch is on. May need to change this setting if switch appears to
be operating backwards)
5) Spindle Setup
i) Select "Use Spindle Motor Output"
ii) Select "PWM Control"
iii) Input "PWMBase Freq." (I used 421)
iv) Input "Minimum PWM" ( I used 0%)
B) Pulley Selection
i) Pulley Number 4
ii) Min Speed = 0
iii) Max Speed = 24000
iv) Ratio = 1
Good luck! Hope this helps!"

Thanks alot. will certainly try these setting and hope it works for me. Cheers
