modbus address register of inverter 3g3tc

2 posts in this topic

Dear all, I have an Omron inverter 3G3TC-AB004, which apparently there is not much information about it online.

I have successfully connected this inverter with Modbus, and able to change some of its parameters from Modbus Poll, yet I still haven't found the address for the Start and Speed Command. I've tried to set the frequency from modbus but unfortunately it's a read only register.

Is it possible to control this inverter from modbus or it's only useful for monitoring the inverter status?

Thanks in advance.

With Modbus Poll try f4 instead of f3.

F3 = function 3. f4 = function 4.

Try with f4, which should let you write to the registers one by one, until you find what you need.

I hope I helped and that you find what you need.
