Using 40 for your max hz and it worked leads me to think it's a formatting issue on how your vfd excepts frequency, although there was a Hitachi X200 user successively using this plugin.

The plugin calculates frequency by dividing your max frequency by your max rpm in plugin configure setup. So for a typical China spindle 400hz/24000 max rpm = 0.0166666666666667


So if you set your rpm to 24000 in UCCNC:

0.0166666666666667 x 24000 = 400<<<<<<<<<<this is was sent to VFD

24000/6 = 4000<<<<<<<<<<<<<<<<<<<<<<<<this is what being sent to VFD

If you have pulleys enabled this will change how the ModbusEZ plugin calculates frequency sent. Unfortunately when developing this plugin there wasn't enough bata testers to find and get all kinks out so I'm sure many will be found.

Thanks for the response Dan.

It is worth mentioning that if I download the X200 manual PDF from Hitachi, that it is different to the printed manual that came with mine.
This caused some confusion for me until I realised it.
There must have been some revision or update of the X200 models.
The differnces that threw me were to do with register number changes.

As I said the Hitachi needs a value between 0 and 4000 in the frequency register.
