Thanks alot, very much appreciated.

According to my supplier this should be the same (Machtric Z900 and S3800)

Tried a couple of different registers, none worked. What do you think Dan ?

This is the problem....Snip from your manual.



ModbusEZ don't send Frequency in a percentage format, the Powertran VFD used this also but gave an alternate option. I would be happy to add an option for this in modbusEZ but I don't own that VFD to test with, possibly send you Single Holdings register strings to test.

Sure, just let me know what to do.
Should be same as Z900 vfd too so you will solve two vfds.

Find keypad frequency set in the vfd parameter manual
Try to use that instead ( work out address from modbus instructions)
Vfd parameter will need to be set to use set keypad frequency not communication

( I used it on ecogoo model - but took a while to work it out)

Can you make a test plugin for me I will try it, set the value to 5000, should be 50%
Thanks!

According to supplier it should be register 1000

mrping, you can test with the ModbusEZ plugin you have as I somewhat explained in previous post. Plugin multiples the frequency by 100 with Frequency resolution check and by 10 unchecked.

With your Max rpm set at 6000 set maxHZ to 100 and check Frequency resolution, this will send 10000(100%) to VFD. Make sure your rpm in UCCNC is set to the max rpm you set in plugin. I will adjust plugin after testing.

I do also suggest following Battwell's advice. The Ecogoo and Powertran both used percent for rpm settings but there were alternate configurations.
Check your manual..... P0.03.

MY modbus notes
Same as I sent you in messenger. ( Cnc machines and parts uk)
Set use keypad for frequency in parameters
Use keypad setting frequency as your modbus and command it in Hz

Finally took some time fixing this and it worked!
Thanks guys
