Regardless how you control your spindle, but for under 10 bucs for a RS485 converter you should really check out the HYPLUGIN. The analog signal can't beat the control you have with the RPM and I implemented reading current Amps thatwill show if cutting under to much load. You can really fine tune your cuts.
I just stuck the Amp field right above the reset button for now for testing.

I think vid should be working now.
I use a shielded 18-2 stranded copper wire, I bought a roll of it in HD when dong limit switches. The Usb sometimes can be hit or miss but that's what most use, I think it could be more susceptible to noise but never used one. If you have a serial connection I suggest that one, no additional drivers needed and never read of any having trouble with it.

I need to use USB with the laptop I'm using, so I just ordered one from Amazon with Sunday delivery, for $7.
So, I just spent two hours testing.
I made a new cable to the spindle, with twisted wires. (Swapped two wires for correct rotation).
I grounded the spindle to the VFD.
I twisted the power cables supplying the VFD (but only after my distribution blocks). There's a heavy cord plugged into the wall before that.
I changed the REV terminal to Forward Rotation (PD045 = 2).
It runs exactly the same as before. Only with the correct rotation, and the FOR LED lit up on the VFD.
I also changed the carrier frequency. It made the motor quieter, but no change in the fluctuations. It was at 3, I changed it to 6. (Also tried 8 briefly)

Dan, is the 11 amps the current that the VFD is drawing?
When I set the VFD to display amps, it shows 1.1-1.4.

No, its the out amps, the current the spindle is drawing, I have a 3kw spindle.
I mentioned in other threads that the HY only reads running frequency for RPM(most...if not all) and if under load it wouldn't show in RPM, the VFD is going to maintain set frequency. The out amps will show/increase under load.
I thought so, but I'll check again next time I run it.

Sorry read and answered to quickly, that seems right although high. The plugin reads set amps(PD142) than adds the out amps. If you have a 2.2kw and have PD142 set to 9 amps than the spindle is drawing 10.1 - 10.4 amps. I'm almost certain I'm interpreting this correctly.When I set the VFD to display amps, it shows 1.1-1.4.
My motor plate reads 11 amps and what's set in PD142. The amp display shows 0 when spindle not running. When running shows averagely 0.0 to 0.2, it increases on acceleration and deceleration.

I think it's set to 8.5amps. The spindle doesn't list the current, but that's what they show in the Ebay listings for the air cooled spindles.

My 2.2kw spindle only draws ~1.7 amps at 24000 RPM with no load. I'm using an Hitachi VFD. If your no load current is 9 amps that seems too high.
PD142 looks to be the spindle name plate amp rating. What ever value is set in this parameter will limit the output of the VFD, is how I read it.

I assumed differently and was incorrect. What threw me off was when my 3kw spindle started at 6000 rpm my readings was 0.0 to 0.1, at 24000 rpm no load readings are 0.4 to 0.6. I didn't think this was possible and lead me to believe what I posted.

Hi Guys,
I came across this thread searching "HY04D023B" as that's the VFD that I ordered. I plan to use this for a 5hp 3 phase old planer.
I haven't even ran wire to mine yet. I would like to run a 20ft cord with a 10-30r nema male plug on it so I can plug it into my dryer outlet. The manual confused the sh** out of me and I've been too busy past week to look further.
I plan to remove the on/off switch on the planer and 'reset' box so the VFD is wired directly to the motor. Is wiring an on/off switch between the wall and VFD needed if I plan to plug and unplug it when needed?
Does anyone have recommended parameters I should use? Might be asking a lot so let me know. A soft start and soft wind down would be good. I won't need variable speed.
The motor is a 5hp 12 full amps draw.

Yeah, the switch is on the machine, then goes to a box that says (reset) then to the motor.
Pic of motor tag. I'd like to run it at it's full 3400rpm. Pic of similar machine below. Mine is belt drive motor, not direct drive, but shows the on/off switch go to a box then motor.
Hi guys.
I noticed my Mach3 and spindle (1.5kW water Cooled) are not working as expected.
The issue is: when I set the spindle speed to the minimum on Mach3, the spindleis is actually spinning at 24000 rpm (top speed).
If I select the Mach3 spindle speed to the full steam ahead, the spindle nearly stops.
I've tested the PWM board signal (0-10v) and the output was 9.9V when the spindle was at 24000rpm - but Mach3 was around 800rpm
The relays are also working (it does spin CW and CCW when demanded.)
So what I did wrong????
Please check the snapshots.
[FIXED]
Dir low active and step low active on spindle's Port & Pins had the wrong value. I unticked both now the spindle is @max speed when Mach3 is @max speed. I hope my silly mistake help this community
