I just shorted XGND to FWD on VFD to check if it starts, now i'm back to using VFD control panel until relay arrives.
Spindle RPM and the frequency display on VFD oscillates quite noticeably at what sounds like around 5-10hz when being controlled by mach3. At full speed it's stable and no oscillation.At this point i've given up on speed control through the software. I've got on/off control and fault estop setup which is fine. It would be nice to figure it out though
Voltage on controller reads a solid number from 0-10v output but it's like the VFD is seeing it as on and off. CHANGING PWM frequency in mach3 makes no difference.
When i probe the 5v pul terminal i can see pulsing on the multi-meter screen, but 0-10v is stable.
Do you know of parameters that could cause this

Parameters i changed are
P00.01 set to 1 to enable run commands?P07.08 set to 3 for frequency
Everything else was set according to how the manual suggests except for 'No.X paragraph frequency P07.00~P07.07'
mine go from 0-400 instead of 50hz to zero that the manual suggests so i left it
