So I have a HuanYang VFD,
When I change PD001 to 0 And PD002 to 0, I can use the VFD to spin up the spindle, no issue and shows the frequency on the VFD.
When I change PD001 to 2 and PD002 to 2, and Send a M3 S1000 I end up with an EOC.n (over current at constant speed).
Any Idea what would cause this ?
I’ve confirmed;
PD014 is 10
PD015 is 10
PD141 is 110
PD142 is 9
PD143 is 2
PD144 is 3600 (also tried at 3000)
also Modbus Screen shows “OK”
Update I can trigger the Spindle by setting
PD001 to 2
and PD002 to 0
This makes me control the speed via the VFD Pot, but at least lets me turn the spindle off and on via Gcode.
It’s a little late, but I just had the same issue, I’d reset the VFD and just copied someone elses settings, instead of noting mine down first.
To cut a long story short, check that your PD025 is set to zero and if it is, you can try changing PD014 (acceleration time) to say 10 seconds (you can always lower it once that is verified to work, I have set mine to 2 seconds), in combination, these two settings soft start the spindle.
If PD025 is enabled (set to 1), it seems to disregard PD014 and instead goes to full speed right away, which results in the overcurrent situation. But too low a value at PD014 does result in the same problem, even if PD025 is disabled.
