trying to get MODBUSEZ to work with macchtric S800E - please help!

[swedishmetalguy]

I'm trying to get MODBUSEZ to work with macchtric S800E, but get "WARNING VFD NOT RESPONDING".

But I have communications as I can see with the serial port monitor.


These are my modbusez settings.


What am I doing wrong?

Thanks so much for contributing this great plugin! Looking forward to starting using my newly converted EMCO PC-Mill 50!

That's and old version of ModbusEZ and you should try downloading the newest version. The serial monitor clip you posted shows the VFD is not responding.

Thanks so much for your reply!

I found a version 16, is this the latest? If not, where can I find the latest, please?
I have now found the correct parameters for the VFD from another member here, but who is using Mach4, not UCCNC.
start cw - decimal 10
stop - decimal 01
start ccw-decimal 06

on/off address decimal 8192
frequency address decimal 8193
Frequency is given with two decimals so that eg 2400 is given as 24000

Which number base is used for the modbusez plugin?
Which are the communication settings that should be used?
I have set 9600,N81, ASCII is this correct? I don't think my communication with the VFD is working correctly, but I don't know how how to troubleshoot modbus, could you recommend a software for sending modbus via serial?

Sorry for all these questions and thanks again for creating the plugin and helping fellow CNC:ers!

Best Regards
Carl

Hi Carl,
All ModbusEZ modbus settings need to be inputted as hex, there are many available converters found with a google search. I written a manual a while back that should answer all your questions. If any more, please don't hesitate to post. I think there is a pic of your VFD model settings in manual.
