Mitsubishi FX3G-60M RS485 Inverter Control

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

Did you try running the drive in manual/local mode?
Are the safety stop signals (S1, S2 and SC) shorted?
