Evening all,
Currently stuck in the office trying to get a working bit of program together for a Mitsubishi FX3G to control two FR-D720S inverters via RS485.
I'm using the FX3U-485ADP Module on the left hand side of the PLC (CH1, I believe).
I've tried using the IVDR blocks to write a frequency and give a run command but the drive isn't responding and the motor hasn't turned as of yet either.
I'm fairly sure I've set the drive parameters correctly. I wondered if anyone could offer some pointers?
Thanks in advance!
Sam
