Hi all...
I just got a 6040 and have it most of the way setup, but I'm now stuck. I followed the very limited directions and have Mach3 controlling X,Y and Z axis, but cannot for the life of me get things set so Mach3 controls the spindle. I saw a previous post where someone was having the same issue, but they never shared their fix. Any help would be appreciated. Attached is the VFD manual that matches my controller, if it helps. Any help is appreciated.
Also wanted to add that I did try these settings I read about in another thread:
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
Did you get this working? I have the same CNC machine and I eventually discovered that the control board supplied with my control box did not allow me to automatically control the spindle from Mach3, it was missing a board and ribbon to connect from the board to the VFD! I contacted the supplier and they sent me the board and wires to connect it! may be your problem too!
Snag96,
Just to make sure, for spindle control you need both pin 1 and pin 17. It seems like you did 17 or 1; need them both.
If I remember right, I put pin 1 as the pulse width signal, and pin 17 as the enable or the direction.
