Huanyang Plugin

[4.2A]

Thank you, Dan!

I'm having a bit of an issue myself trying to control the Huanyang 3kW VFD. I'm using the JBTek 2-wire USB dongle recommended by everyone from Amazon. Attached you will find 1) screenshot of the serial port monitor, 2) my UCCNC profile and 3) settings for my 3kW VFD. What I do know is that my COM4 opens and starts sending data when UCCNC is opened. Upon issuing the RESET and sending S10000, M3, M4 or M5 to MDI does not seem to send anything to the serial port. The only command I see being sent repetitively is 01 01 03 8e 00 00 5c 65.

Few other facts:
1) VFD does have the IC present for RS485 communication
2) I did try swapping the twisted wire polarity
3) VFD works just fine when PD001 and PD002 are both set to 0 and I trigger the spindle to RUN, STOP or REV manually.
4) I am using the most recent version of the plugin from https://www.dropbox.com/sh/hoa7u51d57t4 ... I6ida?dl=0 and it is setup to Call on Startup and Enabled

Please help! Thank you.

The byte array 01 01 03 8e 00 00 5c 65 is what the plugin sends to VFD at start of plugin to confirm communication, if no response the plugin won't continue.

I see you have PD073 set to 120(7200rpm) and your min rpm set to 6000 in plugin. PD073 sets your min frequency allowed in VFD, try increasing your min RPM in plugin configure to 8000 and see if that helps.

Hi Dan: thank you for your prompt reply. As per their manual (screenshots attached) I modified PD011 to be 140 (8400RPM), and PD072, PD073 to be 140 and 300 respectively. I also changed the plugin lower limit to 8400, saved the settings/profile and restarted UCCNC with not additional luck. I have already once RESET the VFD to factory settings already prior to trying all of my efforts.

I'm aware of the many variations of HY manuals out there and why I suggested raising RPM in plugin. If VFD is working as it should from it's control panel the only parameters you should be looking at is for Serial communication(RS-485)

Your Serial Port Data you posted shows your HY VFD is not responding to a call directly to its settings, PD142 (8e hex) and there's a problem in communications. After every written line should show a response in data.

Are you sure it's a Huanyang VFD or a takeoff??

His manual is for a genuine Huanyang.

His manual is for a genuine Huanyang.

Ok... it really doesn't change what I posted. I am interested to read how you came to that conclusion, my Lower Analog Frequency is PD073, this is the same you read all over Zone and what gave me my doubts.

If you read his HY settings he posted PD73 is set to 120, if it was for higher anolog frequency like page of manual he posted it should be 300.

I was mistaken.
I have a .pdf copy of the manual, which I **thought** was exactly the same as the printed manual that came with my VFD.
But looking at the actual printed manual, I see that PD072 and PD073 have the Function column swapped. I think it's just a misprint in the PDF, as the factory setting of 50 is actually for the Higher Analog Frequency.

[ger21]

But it looks like his settings are correct?
PD072 = 300 (Higher Frequency)
PD073 = 120 (Lower Frequency)

I guess we need a pic of the VFD, and the label.

I appreciate you guys helping me this late in the day. I’m already home for the day and right now I only have the pictures of the nameplates on both the spindle and the VFD on my phone which u can see here: https://imgur.com/a/AVcunrP. I will take more detailed pix of the VFD/wiring and post on here tomm. I have also sent an inquiry to the eBay seller solar.jean to try and see if he/she knows anything further about this. I purchased this unit mid-last year (2017) and based on what I’ve read online it should be one of their recent models.

Thank you again!
