Hi,
I am a CNC enthusiast in Canada and am building my most ambitious project todate: a 1.5M X 3.0M CNC Machine with ATC Water Cooled Spindle.
I have come across a problem and hoping for some guidance through this forum.
I have wired up my CNC Spindle and it operates fine through the VFD panel. I also have wired it up to a potentiometer and again it operates as expected. I am having trouble operating it through the AXBB-E via UCCNC.
I am able to operate all three degrees of movement (X, Y, and Z) via UCCNC and have also tested all limit switches. Only the spindle is yet to be automated
First some references:
1. Controller is a AXBB-E which is running a recent version of UCCNC. The manual is easily available on line.
2, VFD is a Sunfar E550-2S0037L. This unit is rated at 3.7KW. 220 V Single Phase. 24000 RPM at 400Hz. The manual is easily available on line.
3. The Spindle is Jiaken JGL-100/2.5R24. This unit is rated at 2.4 KW and is water cooled with pneumatic auto tool changer.
Some background info:
1. Spindle can be run via the VFD Potentiometer Knob
The following config was used:
- AXBB-E A01 pin connected to VFD AI
- AXBB-E 5V0 connected to VFD GND
- VFD Parameter F0.00 = 3
- VFD Parameter F 0.02 = 1000
2. Spindle can be run via an external Potentiometer.
The following config was used:
- Pot Terminal 1 connected VFD AI (10V)
- Pot Sweeper Terminal 2 connected to VFD A01
- Pot Terminal 3 connected VFD GND
- VFD Parameter F0.00 = 1
- VFD Parameter F 0.02 = 1000
As tests 1 and 2 are successful I know the Spindle operates and the Power wiring is good.
3. I have not been successful in operating the Spindle via UCCNC
- I have attached the VFD config used. This is a subset of all config and hopefully I have captured the ones that are significant. The ones I was not sure of are:
F0.00 should this be 1, 2 or 4?
F0.02 should this be 1000 or 1001?
F1.08 should this be 11 to set X1 terminal to Forward
F1.09 should this be 12 to set X2 terminal to Reverse
- I have attached the VFD to AXBB-X wiring diagram
I need guidance on how to wire the VFD CM terminal. I believe this is the digital ground. On my system 5V0 and 24V0 are interconnected. When I check the VFD there is no continuity between the analogue ground (GND) and the digital ground (CM). In some tests I've tried connecting the CM to 24V0 ground and UCCNC does not like this (it creates a limit switch alarm even though the machine is not close to these switches).
- UCCNC Config for this arrangement.
On Spindle Configuration Screen:
- PWM is active
- Spindle relay output is enabled with M3 (FWD) to AXBB-E O7 and M4 (REV) to AXBB-E 08.
On I/O Setup Screen
- Spindle PWM analog ch: set to 1.
Not sure if I am missing anything on the UCCNC Config end.
Any help would be appreciated.
Thanks,
John
