Are there people here who also have a one of those Aliexpress 9600 Series VFD’s?
I’m really stuggling with the manual on how to write Modbus commands to it.
I’d like to achieve the following:
Hi!
Did you make any progress ? I will use the same inverter.
Just in case : the MODBUS Manual.
I would like to achieve the same commands and get the torque or the current.
I kinda gave up on it as I wasnt able to achieve my goal.
What I want is to control it through an ESP32 and a HA input_number so the state is saved upon a lost connection.
I was experimenting with this code, but the number: doesnt respond to the ha_sensor. This appears to be a shortcoming of the number:
Also I found the manual extremely confusing, no idea how to write to a register. The person who wrote this manual used something like google translate, or so it seems,
So now I use a simple 0-10v driver, use the X1 and DCOM for start/stop and a relay to switch it on/of.
I prefer Modbus, but didnt get it working
I see your code, but the address does not seem to be in accordance with http://www.cnweiken.cn/upload/files/20230918/6383065618202112502908477.docx .
Address 0x1000 points to “Communication setup value”.
I used esphome and Modbus already with a boiler without any problem and without most of the time using lambda.
But that’s true that the manual is confusing sometimes.
Yes, the register isnt the correct one, but logs showed that the values werent being sent to the vfd. It probably is possible using an hardwired RS485 interface, but as I need it to be wireless I went for the analog option. Hopefully I will get it to work some day because Modbus gives you much more control over the device. I also have some airco’s that can be Modbus controlled, so I’ll benefit a lot figuring this out.
This was not so obvious… But it’s done. You can go to this discussion . It is in french, but with google, you should not have any problem !
Good luck !
Hi, did you make progress with the Modbus commands?
I have purchased the same VFD, and once I have it in my hands I can jump to this thread and start debugging problems if needed
Hello everyone. I also have two such inverters, which I installed in the ventilation system. I already have a home control system via Modbus (without ESP home). Therefore, I am trying to add inverters to my already working Modbus network. But I encountered a problem: The address system on the inverters has a strange format and I do not understand how to use it in configuration.yaml
I am trying to convert the addresses (2000H - 8192), but I can not do anything. Can someone show an example of commands for configuration.yaml (and without using ESP home)?
Is there really no one who understands Modbus coding? Please! Help me connect these inverters to my system! I am ready to pay for help, because I see that my knowledge is not enough to solve this problem. Please!
