AXBB-E to Sunfar E550 VFD Terminal Connections

[JAZZCNC]

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 use the same VFD's on the ATC spindles we use and sell so below are the settings which work for us.

F0.00 = 1
F0.02 = 1001
F1.04 = 400 (This is the max operating frequency of the spindle when at 10V, the default is 50hz so if you didn't change this when you called for 24,000 rpm the AXBB-E would give 10v but you would only get 3000rpm because to the VFD 10v = 50hz)
F1.08 = 11
F1.09 = 12

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.

Well, the Setup is correct regards 0-10V
All you need for 0-10v analog output on AXBB-E is PWM Spindle enabled in Spindle Config, none of the settings in PWM matter, and Spindle PWM ->analog ch=1.

Break this down into 2 parts for testing, so start with speed control first and leave F0.02 = 1000 and start the spindle from the VFD panel but control the speed from UCCNC software.
Connect Axbb-e AO1 to VFD AI and Axbb-e 5v0 to VFD GND

Then look at the Start/stop.
Now I don't use the Axbb-E Outputs directly to the VFD inputs and prefer to control relays using the outputs. This way I can use spare contacts on the relays to do other things like turning water pumps on or external Led's etc.
In this case, we just connect 24V+ to relay coil (V+) and output O2 to the (0v) coil then run VFD CM to the Com contact and X1 to the NO contact.
I only ever use forward rotation so don't bother with reverse because mostly using ER collet holders which are not safe to run in reverse.

I can't really help with the direct to output setup but I also can't see why it wouldn't work because all the output is doing is providing a path to 24v-0v and with 24V-0v connected to CM then all your doing is shorting X1 to CM which should start the VFD.?

Maybe try separating the 24-0 and 5v-0 just in case you are getting feedback.?
