Advantages of SINAMICS V20 VFDs. SINAMICS V20 VFDs are versatile drives for basic applications. Integrated pushbutton interface also makes parameterization and installation a breeze. If you need an easy to commission, low cost, and durable VFD for easy applications, then the V20 line from Siemens is the perfect line for your application.

Hello everyone,

I'm trying to use an arduino Duamelinove to comunicate with a Sinamics V20 inverter via RS485. I have a shield to convert the RS232 from the arduino to the RS485 from the inverter. I also have a RS485/USB adapter to monitor the communication from a computer.

I've loaded the SimpleModbusMaster library example on the arduino, and I'm getting transmission errors on the computer monitor (values different from what was transmited). The inverter receives the signal, but it returns a 'parity error'.

I also tried communicating the inverter with the computer, without the arduino, using a Modbus Master demo and, this time, it returns a 'character structure error'.

Has anyone ever tryied to do something similiar before? I'm not sure if this is even possible as everything I find online mention only communication between Siemens Inverters with Siemens PLCs.

Any thoughts would be appreciated.
