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.
Motor Braking module Resistor SINAMICS V20SINAMICS V20 feature Your benefits The dynamic energy is dissipated as heat in a braking resistor with an adjustable duty cycle of between 5% and 100%. Possible to use dynamic braking to increase braking performance. Inverters ≥ 7.5 kW have an integrated braking module. SINAMICS V20 Inverter Getting Started, 07/2012, A5E03728127 3 Preface Purpose of this manual This manual provides you with information about the proper installation, quick commissioning and basic operation of SINAMICS V20 inverters. SINAMICS V20 user documentation components Document Product Language Inverter system. Modbus SINAMICS V20 Standard library The communication port is available at terminals. The preset parameters of the USS and Modbus RTU are defined in the connection macro. N Easy integration into existing systems n Easy integration into micro automation systems n.
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.
